Comment (by ryandesign@…):

 Replying to [comment:7 nick@…]:
 > Ok, thanks for your -very- elaborate explanation. Indeed p5.16-template-
 toolkit was installed. I guess I am getting confused by the fact that
 multiple Perl versions can be installed simultaneously.

 This was intended to be a convenience to users who needed a specific
 version of perl. We do the same for other language ports. However, in the
 case of perl5 we're having some debate as to whether we want to continue
 offering multiple versions. There are pros and cons.

 > I tried to fix all other ports the same way, but ended up uninstalling
 all Perl ports and reinstalling the ones that I could remember (I'll find
 out incrementally what I need eventually, so it's not that big a deal).

 That'll work.

 > Thanks again! This text should be contributed to a FAQ.

 It wasn't documented before because I didn't realize the problem existed
 until I reread your ticket description and wrote my response. When
 designing the current perl5 portgroup we probably didn't anticipate that
 variants of the perl5 port would ever be removed; it was the removal of
 the old variants that caused the problem you experienced. I would rather
 fix the problem than document it, but it may be hard to fix.
