Problem compiling

Hi.  I'm trying to compile Postgresql on a Sparc 20 running.. Solaris 2.6
I think. However, when I run configure in src, the following happens:

$ ./configure
loading cache ./config.cache
checking host system type... sparc-sun-solaris2.4
checking echo setting...
checking setting template to... solaris_sparc_gcc
./configure: conftest.sh: not found

Whoops. Hm.. That says solaris 2.4. I didn't think it was THAT out of
date. I suppose that this would be my problem? Aside from upgrading the
OS, is there a specific program that needs to be updated, ect?

Thanks for any help you can provide.
