It does not need perl. The problem is with doc/Makefile.

The only use of perl here is to build usersch3.tex from src/desc/pari.desc, but
if usersch3.tex is shipped but not src/desc/pari.desc, then certainly perl is useless.

The issue is that the Makefile try to "update" usersch3.tex even if no files in
src/functions/*/* are modified. The patch I sent fix that.

Hope that clarify,

Cheers,
