Code:
Version 8.30 04-February-2012
-----------------------------

1.  Renamed "isnumber" as "is_a_number" because in some Mac environments this
    name is defined in ctype.h.

2.  Fixed a bug in fixed-length calculation for lookbehinds that would show up
    only in quite long subpatterns.

3.  Removed the function pcre_info(), which has been obsolete and deprecated
    since it was replaced by pcre_fullinfo() in February 2000.

4.  For a non-anchored pattern, if (*SKIP) was given with a name that did not
    match a (*MARK), and the match failed at the start of the subject, a
    reference to memory before the start of the subject could occur. This bug
    was introduced by fix 17 of release 8.21.

5.  A reference to an unset group with zero minimum repetition was giving
    totally wrong answers (in non-JavaScript-compatibility mode). For example,
    /(another)?(\1?)test/ matched against "hello world test". This bug was
    introduced in release 8.13.

6.  Add support for 16-bit character strings (a large amount of work involving
    many changes and refactorings).

7.  RunGrepTest failed on msys because \r\n was replaced by whitespace when the
    command "pattern=`printf 'xxx\r\njkl'`" was run. The pattern is now taken
    from a file.

8.  Ovector size of 2 is also supported by JIT based pcre_exec (the ovector size
    rounding is not applied in this particular case).

9.  The invalid Unicode surrogate codepoints U+D800 to U+DFFF are now rejected
    if they appear, or are escaped, in patterns.

10. Get rid of a number of -Wunused-but-set-variable warnings.

11. The pattern /(?=(*:x))(q|)/ matches an empty string, and returns the mark
    "x". The similar pattern /(?=(*:x))((*:y)q|)/ did not return a mark at all.
    Oddly, Perl behaves the same way. PCRE has been fixed so that this pattern
    also returns the mark "x". This bug applied to capturing parentheses,
    non-capturing parentheses, and atomic parentheses. It also applied to some
    assertions.

12. Stephen Kelly's patch to CMakeLists.txt allows it to parse the version
    information out of configure.ac instead of relying on pcre.h.generic, which
    is not stored in the repository.

13. Applied Dmitry V. Levin's patch for a more portable method for linking with
    -lreadline.

14. ZH added PCRE_CONFIG_JITTARGET; added its output to pcretest -C.

15. Applied Graycode's patch to put the top-level frame on the stack rather
    than the heap when not using the stack for recursion. This gives a
    performance improvement in many cases when recursion is not deep.

16. Experimental code added to "pcretest -C" to output the stack frame size.

I installed this today as it was added to custombuild. But my httpd wouldn't compile after it.

server/.libs/libmain.a(util_pcre.o): In function `ap_regcomp':
/usr/local/directadmin/custombuild/httpd-2.2.22/server/util_pcre.c:140: undefined reference to `pcre_info'
collect2: ld returned 1 exit status
make[1]: *** [httpd] Error 1
make[1]: Leaving directory `/usr/local/directadmin/custombuild/httpd-2.2.22'
make: *** [all-recursive] Error 1

*** The make has failed, would you like to try to make again? (y,n):
So I've reverted back to pcre .21.

I've googled it and seems to be a bug:
https://issues.apache.org/bugzilla/show_bug.cgi?id=52623

and the fix was proposed for httpd 2.2, but I guess it isn't been added just yet. 2.4 should be fine if I understand correctly.

Busca primero el archivo de pcre-config, una vez que lo encuentres (whereis pcre-config o find / -name pcre-config), tienes que poner el parametro de --with-pcre en la configuracion, es decir.
./configure --with-pcre=/usr/bin/pcre-config
