The extension you are trying to build apparently is rather old and
most probably outdated. We detect that from the fact, that a
subroutine "writeMakefile" is called, and this subroutine is not
supported anymore since about October 1994.
Please contact the author or look into CPAN (details about CPAN can be
found in the FAQ and at http:/www.perl.com) for a more recent version
of the extension. If you're really desperate, you can try to change
the subroutine name from writeMakefile to WriteMakefile and rerun
'perl Makefile.PL', but you're most probably left alone, when you do
so.
