[Slackbuilds-users] lablgtk SlackBuilds install overwrites ocaml ld.conf

[Jason Graham]

Hi Matteo, thanks very much for preparing the patch.

I should also note/clarify that preserving the original ocaml ld.conf file
fixes the dllunix.so error when building unison. There is still a gtk2
error during the unison build, but this is addressed in a previous posting:

Jason
