That did the trick. Many thanks!!
Now I don't seem to have "memclr" in my library paths. The "helper" program that's used in Makefile.PM outputs "-L/usr/local/lib" which goes into the LIBS array.
Do you (or anyone) know if memclr is deprecated in favor of memset?
With an eye toward CPAN, I wouldn't want to use a library function that people don't have in standard libraries...
