Themis,

Because I can't see your screen, you must redirect both the standard
output AND the standard error streams to the files that you send me.
The mechanism to do this depends on your user-shell:

    Standard-conforming shells:

        make >make.log 2>&1

    csh-like shells:

        make >&! make.log

It appears from the above that your C runtime library doesn't contain
the standard C mathematical functions.  They are probably in a 
separate math library (libm.a or libm.so).  Please 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 so that it
        contains an ld(1) reference to the math library.
        For example:

            export LD_MATH=-lm

    5.  Proceed with the rest of the build process beginning
        with the "configure" command.  Redirect both the 
        standard output AND standard error streams into the
        output files.

Steve Emmerson
