It looks like the C math functions aren't in the standard C runtime library.  
Try this:

1. Go to the top-level source-directory.

2. Execute the command "make distclean".

3. Set your environment variables as before.

4. Set the environment variable LD_MATH to "-lm".

5. Proceed with building the package as before starting with the execution of 
the configure(1) script.

Steve Emmerson
