I'd agree with that - if introducing an additional dependency isn't an issue.
I guess that the set of compression formats to recognise is limited and rather well-known, so alternatively a home-grown solution could be used. I've implemented something like that for an old "less" version long ago that I've been maintaining (because I never felt like porting it to newer versions =)). I'd be happy to donate that code so it can be bundled in a little Tcl package - that way it should be relatively straightforward to implement an updating mechanism for just that extension if ever a need arises to support new formats without requiring a full MacPorts upgrade.

On a related note: didn't I hear/see discussion about the possibilities of providing certain features as (more or less obligatory) ports?
