Not bad. I just found that configure sets the variable $(PERLPATH) when a perl program was found. Then each Perl part of groff can use that variable in its Makefile.sub for testing the Perl version with $(PERLPATH) -e 'require v...'. That would work with make. But so far I do not know what to do when $(PERLPATH) is empty (no Perl program found) or if the version is wrong. Bernd Warken
