Compilation on Solaris 2.8

Hi :

I am having problems in compiling Postgres 7.1.
I am using the following compilers on Solaris 2.8 on a  Sparc Ultra 60
machine.

Sun WorkShop 6 update 1 C++ 5.2 2000/09/11
Sun WorkShop 6 update 1 C 5.2 2000/09/11

Is there a port available for this configuration ?

Thanks,
Manoj Nair
