The information on <http://pdb.finkproject.org/pdb/package.php/mc> is currently incorrect: It claims that 18.104.22.168-1 is the latest unstable version for 10.5 and 10.6, but in reality 22.214.171.124-1 is the latest unstable *and* stable version across all 10.5 configurations.
This is because the PDB script looks at 10.4-EOL/gnome/mc.info for these systems, which contains an old version, and uses that in the database.
But this is wrong:
a) It should not look at 10.4-EOL when generating data for systems 10.5 and upwards
b) It should not let one .info with an old version override the data from another .info with a newer version.
