The above message contained the following:

> Output of "make install"
> 
> make  =/usr/local/lib LIBDIR==/usr/local/lib
> make: *** empty variable name.  Stop.
> make: *** [install] Error 2

Apparently, the makefile macro LIBDIR is defined as "=/usr/local/lib" in
the makefile "port/misc/Makefile".  The equals-sign prefix is causing
the problem.  Why it has an equals-sign prefix is a puzzle.

It could happen if the "--prefix" option of the "configure" script was
specified with an extra equals-sign, e.g.

    ./configure --prefix==/usr/local

This can be checked by going to the top-level source directory and
executing the command

    grep exec_prefix config.status

If that's the case, then you'll have to do another "make distclean" and
rebuild the package.
