Macports might itself treat the epoch and revision as different things to the package version, which of course they are, but third parties cannot really be expected to understand such nuances. In this case the pkg's created need a single version number I think, so the version constructed for them have to include the epoch and revision numbers, if the system is to properly support changes in them. I don't think this situation is that different to rpm/deb packages on Linux systems, which usually do something very similar, combining the native package version with other versionings.

A 1_3.2.0_0 style version number won't work with Apple's version number, 
which can only accept digits, so I do the following:

   v = "${epoch}.${version}.${revision}

   # Convert anything besides a period and number to a period.
   v =~ s/[^.0-9]+/./g

   # Replace multiple periods with a single period.
   v =~ s/\.+/./g

   # Trim trailing periods.
   v =~ /\.+$//

So for scala2.10's 2.10.0-RC5 release with epoch 0 and revision 2, it 
becomes 0.2.10.0.5.2.  I don't know if Apple knows how to handle more 
than 3 integers, but according to the Munki people, they support this 
and will install an updated version.
