Comment (by mfeiri@…):

 Oh, when I created this patch there was no support for hfsCompression in
 libarchive. I just noticed that a couple of weeks later "experimental
 support for HFS+ Compression" was added to libarchive. Yay! I guess this
 means we can get rid of the additional round of i/o. Would you suggest to
 somehow depend on our port of libarchive or to import libarchive/bsdtar
 into the base macports distribution?

 I would have assumed that for the kinds of files installed by macports
 (text and executables) the cost/benefit tradeoff is clearly in favor of
 unconditionally enabling compression. Apple also uses hfsCompression in
 /usr/bin and similar locations. Once I have some spare time again I will
 look into extending the patch to allow to opt out of hfsCompression.
