man now supports lzma-compressed manpages. That's fine, but lzma is not in @base, so installing just @base results in a system which cannot run man. Suggest adding lzma to the @base group.
Are all man pages made in lzma now, or only some? Are you getting a crash or an error? Would this be better solved by a package requirement rather than a comps forcing?
AFAICT man saves its cached pages in lzma format now. Or it tries to. The strange part is - this only happens when I'm logged in at the console. The error is: sh: /usr/bin/lzma: No such file or directory Error executing formatting or display command. System command (cd /usr/share/man && (echo ".pl 1100i"; /usr/bin/gunzip -c '/usr/share/man/man1/ls.1.gz'; echo ".\\\""; echo ".pl \n(nlu+10") | /usr/bin/gtbl | /usr/bin/nroff -c -mandoc 2>/dev/null | /usr/bin/lzma > /var/cache/man/cat1/ls.1.lzma) exited with status 32512. Yes, you could also fix this by making man require lzma.
Fixing it with requires seems like the right thing to do, especially for people who install and fiddle with groups or whatnot. If man is going to use it, it needs to require it.
