We already use perl for TEXI->POD, POD->MAN and TEXI->HTML depend on a
perl script, so no, in practice we already require the presence of
perl for MAN and HTML output generation.

Practically this means that I should probably extend the dependencies
like this:
podpages_deps="perl"
manpages_deps="pod2man"      => "perl podman"
htmlpages_deps="texi2html"   => "perl texi2html"
txtpages_deps="makeinfo"     => "perl makeinfo"

Right now in a system with no perl we are able to create TXTPAGES
only, that is fate.txt. Maybe I could implement the script in awk, but
I'm not familiar with that language and it would require more time for
me to write and maintain.
