For an instance, see bug #74929. This happens with the latest version of portage. Doman properly gzips the manpages.
Just an FYI, this bug is preventing most of the current porting efforts.
Steps to Reproduce:
Does portage gzip manpages on any OS? I thought it did, but I can't find any code to do so...
it must happen on linux because it does it on every box of mine ;)
The fix for this is already in CVS thanks to ferringb.
Unfortunately, we're still waiting on a release for this to get to our userbase.
To put this in perspective, currently every package that gzips manpages
is broken on OSX pending this bug getting fixed.
*Please* can we get this out soon?
fixed with portage-184.108.40.206
