Description:
------------
Trying to install PHP5 with Interbase support, I encountered the same problem as many of PHP users. But the strange errors 
/usr/lib/libgds.so: undefined reference to `write@GLIBC_2.0'
makes me think I need glibc, which is not ported to FreeBSD.
How can I evade this problem? (if I can).

Reproduce code:
---------------
configure: error: libgds, libib_util or libfbclient not found! Check config.log for more information.
