Hi,

Why are you trying to compile gcc? By default it's already installed under /usr/sfw/bin. If you don't have it, you can use your installation media to install it. Then change your PATH to:
Or you can get the one from sun freeware and you pkgadd to install it, along with its dependencies

Regards
