What makes you think it isn't open-source? The source is freely available from the Mandrake-sources trees. I think the reason it may have less visibility in the Perl community has to do more with the fact that it isn't Perl. Not to denigrate OCAML (I don't know enough about it to make a judgement), but it seems that Perl developers tend to like using development tools written in Perl.
I know that's my preference, and for me it has largely to do with the potential need to modify the tools -- when I'm in "Perl mode", it would be far easier for me to make a tweak to a Perl-based tool than, say, a C-based tool.
