git has those terrible deps:
:: openssl zlib perl python rcs
cogito may add in the mix
:: curl and rsync
mercurial has those terrible deps:
:: python and asciidoc xmlto for the documentation
subversion has those terrible deps:
:: apr-util optionally apache, every language known, neon, db4
Depending on your tastes about source or prebuilt:
- svn takes lots of time to build
- svn may be distributed with lots of deps
- the default git and mercurial implementation use python and/or perl
for some or all tasks so it takes the time to have those built or, if
you already have them, it takes just the time to fetch and unpack them.
