Interbase php installation problem

Hello
I try to use Interbase Client with PHP to work with an interbase database. 
I work on Solaris 8, with php 5.1.4 and apache 2.0.55.
So, I have to recompile my php with the option:
"--with-interbase=shared,/opt/app/apache/SoftAnx/Interbase/7.5"
The compilation fails with the following error message :
...
checking for isc_detach_database in -lib_util... no
configure: error: libgds, libib_util or libfbclient not found! Check config.log
for more information 

In the config.log, I has the following error :
...
configure:49496: checking for isc_detach_database in -lib_util
configure:49515: gcc -o conftest -I/usr/local/include -g -O2 
-D_POSIX_PTHREAD_SEMANTICS -R/opt/app/apache/SoftAnx/Interbase/7.5/lib

/* Override any gcc2 internal prototype to avoid an error.  */
/* We use char because int might match the return type of a gcc2
    builtin and then its argument prototype would still apply.  */
char isc_detach_database(

The 3 libraries :libgds, libib_util and libfbclient are wel installed and my
LD_LIBRARY_PATH is correct...

Thanks for help

As noted in another thread, it appears the InterBase client cannot be found.
