Solaris 8 ./confgure problem.

I'm trying to build Postgresql on my Solaris 8 Sparc box. After I set the
CC variable to point to
my /usr/local/bin where I installed my gcc, I get the following error when
I run the ./configure script.

# ./configure
loading cache ./config.cache
checking host system type... sparc-sun-solaris2.8
checking which template to use... solaris
checking whether to build with locale support... no
checking whether to build with recode support... no

checking whether the C compiler (/usr/bin ) works... no
configure: error: installation or configuration problem: C compiler cannot
create executables.

I think that I've see this error before, but not sure where. Can someone
tell me
what I need to do to build Posgresql on my Solaris server?
