Serkan,

Please disregard my previous reply.  Your subsequent email indicated the
problem.

(Aside: your email was formatted strangely.)

It appears that your gcc(1) installation doesn't automatically supply
the Standard C math functions pow(3) and log10(3).  This is incorrect
behavior and indicates an improper gcc(1) installation.

You'll either have to correct the gcc(1) installation or locate
those functions.  If you do locate them, then add a reference to the
containing library to the LIBS environment variable before (re)executing
the "configure" script.  For example, from the top-level
source-directory:

    make distclean
    export LIBS='-L/opt/gnu/gcc3/lib/libm.a -lm'        # example
    export ...                                  # additional settings
    ./configure >configure.log 2>&1
    less configure.log
    make >make.log 2>&1
    less make.log
    make test >test.log 2>&1
    less test.log
    make install >install.log 2>&1
    less install.log
    make clean
