I have a mono-based package called "lat", which I believe follows the current packaging guidelines, i.e. it installs lat.exe and its associated DLLs into %{_libdir}/lat.

The package has dependencies on some mono packages from Core, particularly avahi-sharp. On x86_64, the avahi-sharp package contains:

/usr/lib/mono/avahi-sharp /usr/lib/mono/avahi-sharp/avahi-sharp.dll /usr/lib/mono/gac/avahi-sharp /usr/lib/mono/gac/avahi-sharp/1.0.0.0__4d116c78973743f5 /usr/lib/mono/gac/avahi-sharp/1.0.0.0__4d116c78973743f5/avahi-sharp.dll /usr/lib/mono/gac/avahi-sharp/1.0.0.0__4d116c78973743f5/avahi-sharp.dll.config /usr/lib/mono/gac/avahi-sharp/1.0.0.0__4d116c78973743f5/avahi-sharp.dll.mdb /usr/lib64/pkgconfig/avahi-sharp.pc

So avahi-sharp.dll is in /usr/lib rather than %{_libdir}

When I try to start lat on x86_64, I get:

$ lat lat [09776] INFO Starting lat (version 1.2.1.1)

** (lat:9776): WARNING **: The following assembly referenced from /usr/lib64/lat/lat.exe could not be loaded: Assembly: avahi-sharp (assemblyref_index=14) Version: 1.0.0.0 Public Key: 4d116c78973743f5 The assembly was not found in the Global Assembly Cache, a path listed in the MONO_PATH environment variable, or in the location of the executing assembly (/usr/lib64/lat).

I can work around this though:

$ MONO_PATH=/usr/lib/mono lat

That works.

So my question is: is my package in error, or is it avahi-sharp? Should I set $MONO_PATH in /usr/bin/lat?
