C compiler cannot create executables
 

Okay, I finally appear to have gotten gcc working. Now I am trying to install Mailman but get this error

[root@inannasgarden mailman-2.1.4]# ./configure
checking for --with-python... no
checking for python... /usr/bin/python
checking Python interpreter... /usr/bin/python
checking Python version... 2.2.2
checking that Python has a working distutils... yes
checking for a BSD-compatible install... /usr/bin/install -c
checking whether make sets $(MAKE)... yes
checking for true... /bin/true
checking for --without-gcc... no
checking for gcc... gcc
checking for C compiler default output... configure: error: C compiler cannot create executables
See `config.log' for more details.

Help!!!!!

What does it say in config.log?
You could try creating a small c program and compiling with gcc to make sure it is installed correctly.
