Looks like you'll need to tell the build procedure to use a
particular math library.

Assuming that the missing functions are in the "m" library (e.g.,
/usr/lib/libm.a), then try the following:

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

2.  Execute the command "make distclean".

3.  Execute the "configure" script with at least the following
    arguments:

    ./configure CPPFLAGS=-D_XOPEN_SOURCE=500 LD_MATH=-lm

    If you don't want or need the Perl interface, the add the
    following argument:

        PERL=''

4.  Execute the command "make"

5.  Execute the command "make install".
