It looks like the C mathematics function floor(3) isn't in the default
C runtime library --- which is odd because the function sin(3) does
appear to be in that library.  Oh well.

You'll need to rebuild the package from scratch with the environment
variable LD_MATH set.  Try this:

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

2. Execute the command "make distclean".

3. Set any environment variables as before.

4. Set the environment variable LD_MATH to reference the C math library.
for example:

    export LD_MATH -lm

5. Continue as before starting with executing the configure script.
