Enable support for lzip
Last modified: 2012-07-10 14:32:04 EDT
man-db 2.6.1 has support for lzip compressed man pages, "BuildRequires: lzip" would compile that in. Just like xz, no need for a Requres for it IMO.
You should be able to use --with-lzip=lzip rather than adding a BuildRequires; likewise for other such tools.
