error when use this command /usr/local/directadmin/custombuild/build versions

I would like to know which version of my directadmin

# /usr/local/directadmin/custombuild/build versions
mail-header-patch=yes is set in the options.conf, but is not required with this php version.
To enable the X-Mail header, set mail.add_x_header to 1 in your php.ini
/usr/local/directadmin/custombuild/build: line 7471: unexpected EOF while looking for matching ``'
/usr/local/directadmin/custombuild/build: line 7472: syntax error: unexpected end of file

./build set mail-header-patch no

Then manually set mail.add_x_header to 1 in your php.ini, then restart apache

then ./build versions

Then manually set mail.add_x_header to 1 in your php.ini

If everything is oke, then this should be default to 1 in new installs.
But ofcourse it's best to check.
