configure apache php with gmp

[jaybar]

I am attempting to build a new apache to include some additions to php. We are adding the --with-gmp option to php's ./configure. The ./configure works without the gmp option, but does not complete when we add the --with-gmp option.

Here is some more detailed info:
OS hpux11
apache version 1.3.20
php version 4.0.6
gmp version 4.0.1
openssl version 0.9.6b
mod_ssl version 2.8.4-1.3.20

Here is the configure options I am sending:
---------------------
$ ./configure --with-apache=/apache/apache/apache_1.3.20 --with-oci8 --with-oracle --with-ndbm --with-db --with-gmp --enable-ftp
---------------------

Here is the error I am receiving:
---------------------
checking for gmp support... yes
configure: error: Unable to locate gmp.h
---------------------

I viewed php's configure script and here is the line where the error occurs:
----------------------
for i in /usr/local /usr $PHP_GMP; do
if test -f $i/include/gmp.h; then
GMP_DIR=$i
fi
done

if test -z "$GMP_DIR"; then
{ echo "configure: error: Unable to locate gmp.h" 1>&2; exit 1; }
fi
----------------------

It appears that it is looking for the gmp.h file in the /usr/local dir but I put the file there and even added the dir to my .profile but I still cannot get past that error. I also copied the gmp.h file to the php base dir in /ext/gmp.


Any help would be extreamly appreciated.
Thanks,
Joe
