All of those gdbm_* functions are implemented in the files under
gdbmobj, which should produce libgdbmobj.a.  If you look at the
configure.in for makedat, you see:

case "$db" in
gdbm)
        USE_GDBM=1
        USE_DB=0
        LIBDB=""
        dblibrary=../gdbmobj/libgdbmobj.a
        ;;
db)
        USE_DB=1
        USE_GDBM=0
        LIBGDBM=""
        dblibrary=../bdbobj/libbdbobj.a
        ;;
*)
        makedatprog_target=""
esac

...then in Makefile.ac you have:

makedatprog_LDADD=@dblibrary@ @LIBGDBM@ @LIBDB@

...all of which means that:

1. the make should build the stuff in gdbmobj dir (resulting in
libgdbmobj.a) before entering makedat;
2. the link command for makedat should have libgdbmobj.a on its command
line so that it can find the functions that are showing up as missing.

The initial _ is nothing to worry about, that happens to all C
functions.

If you are going to figure this out you have to make sure that both 1
and 2 are happening.

You DO have the 'libgdbm-devel' package installed, right?
