Pull in area51's otter changes which upate otter to it's april beta release. Also, the www/otter-browser port currently doesn't install most files that it puts into stagedir, which gets fixed by this commit.
Unit Tests Skipped
Already tried doing so in September last year:
Otter doesn't compress it. I could do so explicitly, but then it should probably also go to man/man1 instead of share/man/man1.
The compress-man target compresses all man pages automatically, so you shouldn't need to worry about this. Now I'm glad you mentioned the path thing, the man pages should be installed to /usr/local/man, not /usr/local/share/man.
