Installing PHP on Solaris (Express) Error

Hi PHP 5 can't seem to find cc compiler even though it's there
(note, i'm installing in a zone,& am root)
Any Ideas ?

$ pwd
/tmp/php-5.2.6
$ ./configure
loading cache ./config.cache
checking for Cygwin environment... no
checking for mingw32 environment... no
checking for egrep... egrep
checking for a sed that does not truncate output... /usr/bin/sed
checking host system type... i386-pc-solaris2.11
checking target system type... i386-pc-solaris2.11
checking for gcc... no
checking for cc... no
configure: error: no acceptable cc found in $PATH
$ echo $PATH
/usr/bin
$ ls -l cc*
lrwxrwxrwx 1 root root 20 Mar 10 16:36 cc -> /opt/SUNWspro/bin/cc
lrwxrwxrwx 1 root root 24 Mar 10 16:36 cc-5.0 -> /opt/SUNWspro/bin/cc-5.0
$ pwd
/usr/bin

What says:

ls -lL /usr/bin/cc

?

is your $LD_LIBRARY_PATH set? pointing to all the appropriate libs and such.

A search for C compilers on the system, such as cc or gcc will show their paths.. add them to the path and echo $PATH to verify. it should work aft that

Depending on what choice was made as installation type (core, end-user, developer, full), Solaris Express can have no, one or two C compilers.
Contenders are /usr/sfw/bin/gcc (not in the default PATH) and /opt/SUNWspro/bin/cc (neither in the default PATH). Perhaps SUNWspro isn't installed at all or isn't installed as a package so /opt/SUNWspro just doesn't exists in the sparse zone which doesn't lofs mount /opt, the reason why I asked for the ls -lL result.
