There is two separate issues:
1. ghc-7.10 became less chatty when loads libraries.
'ghci -v2' gets it back with a bit of noise
2. looks more like actual problem. is your mylib
fully linked against it's depends?
LD_LIBRARY_PATH=/the/path ldd -u /path/to/mylib.so
LD_LIBRARY_PATH=/the/path ldd /path/to/mylib.so
you can also try to inspect LD_DEBUG=help ghci ...
