postgreSQL installation failed

currently, i am running a 64bit SuSE 11.1

i download the source code from postgreSQL official site
(the source code is compatible with my 64bit linux? )

But when type in

./configure

it ends up with this:

“No acceptable C compiler found in $PATH”

after check the installed software, i found the 32 bit gcc c compiler located in /lib
and 64 bit gcc c compiler located in /lib64

what is the problem then? should i change to 32bit SuSE linux?

thanks in advance

You do know that openSUSE also has postgresql packages so you didn’t have to compile?
