Christopher,

The file "make.log" contained the following:

...

Apparently, your math functions aren't in the C runtime library.

They're probably in the "m" library.  Try the following:

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 reference the math
library, e.g.,

        LD_MATH='-lm'; export LD_MATH

    You can use the "nm" utility to verify that the "m" library does,
    indeed, contain the missing math functions, e.g.,

        nm -g /usr/lib/libm.so | grep floor

5.  Continue with building the package as before, starting with executing
the "configure" script.
