python - Mac OS X echo $PATH gives strange directory. Xcode installed right?

Question

I am trying to figure out if Xcode was installed right because I am having trouble compiling a C program on my Mac OS X Mountain Lion. Why is the output of echo $PATH having anything to do with Python.framework?

Shanes-MacBook-Pro:all_dsc chimpsarehungry$ echo $PATH
    /Library/Frameworks/Python.framework/Versions/Current/bin:/sw/bin:/sw/sbin:/Library/Frameworks/Python.framework/Versions/3.2/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/local/git/bin:/usr/X11R6/bin

I started researching this problem of having Xcode installed right because I get the following error when I try to compile a C program.

Shanes-MacBook-Pro:all_dsc chimpsarehungry$ gcc main.c
Undefined symbols for architecture x86_64:
  "_output_res", referenced from:
      _main in cc1YZOoj.o
  "_pred_acc", referenced from:
      _main in cc1YZOoj.o
  "_predict_sequence", referenced from:
      _main in cc1YZOoj.o
  "_read_sequence", referenced from:
      _main in cc1YZOoj.o
ld: symbol(s) not found for architecture x86_64
collect2: ld returned 1 exit status

I get a similar error when I type 'make'. I am brand new to this. I will post a question about running C programs and compiling in the future. But for now, I just want to address this weird directory I get.
