We have to be a bit patient with Debian testing at the moment, it's
gummed up because libc6 hasn't been sufficiently bug-free in months.

The libpng2/3 transition was particularly ugly because of the complete
lack of ABI compatibility, and of the many things it touched. (e.g.
libgtk, hence all of GNOME) In this case, mtrg is directly using
libpng3, while loading a library that uses libpng2, or similar. Ugh.

So... speaking to everyone, try to keep mussel as clean as possible in
the interim, and if downgrading a package, or compiling the
One-Vital-Thing-I-Need-Now-Fresh-From-CVS into /usr/local, will
simplify things - consider that.  If you're upgrading, do a bit at a
time, and don't worry - if it breaks, it can be fixed, if you tell
someone.
