Hi,

I couldn't as yet find out why several Ocaml-related packages did not
build correctly with the latest version(s) of ocaml. I did not recognize
the ld.conf issue.

Thanks for pointing that out. And thanks to Matteo for the patch. I hope
this fixes also the issues I experienced when trying to upgrade the
Ocaml-Slackbuild to the latest version.

Markus
