I'm not sure this is the same error.
I do see that libtool is getting compiled and it ends with:
make[3]: Leaving directory `/usr/local/directadmin/custombuild/libtool-2.2.6a'
make[2]: Leaving directory `/usr/local/directadmin/custombuild/libtool-2.2.6a'
make[1]: Leaving directory `/usr/local/directadmin/custombuild/libtool-2.2.6a'
Done Libtool
