There is a very good reason for this -- Mozilla's ABI is very
unstable. Multiple Mozilla-based apps (Firefox, Thunderbird, Mozilla
suite, Seamonkey, GRE etc) and their different versions will cause a
lot of conflicts unless kept completely separate. For example, when I
added my Mozilla directory to ld.so.conf, Firefox couldn't run.

This is not really a problem with GtkMozEmbed itself, but the XPCOM
libraries upon which it relies, so Gecko# consumers should generally
not have to worry where libgtkmozembed.so comes from. Anything using
XPCOM will often have problems unless using exactly the same version
agains which it was linked.

Several Gecko#-consuming apps, e.g. Monodevelop, aspnetedit, etc set
LD_LIBRARY_PATH in their launch script.

AspNetEdit has a fragile (XPCOM) dependency, so detects the Mozilla
directory in the configure script and writes it into the launch script
http://svn.myrealbox.com/viewcvs/*checkout*/trunk/aspeditor/configure.in
and http://svn.myrealbox.com/viewcvs/*checkout*/trunk/aspeditor/script.in

Monodevelop is currently more flexible, so detects it in the launch
script: http://svn.myrealbox.com/viewcvs/*checkout*/trunk/monodevelop/monodevelop.in
I think that this latter method could be a good Banshee-wide thing to
have. Note that MOZILLA_FIVE_HOME seems to be a semi-conventional
environment variable to specify the libgtkmozembed directory.

The number of times I've talked about this problem with Gecko#, I
should really write a wiki page ;-)
