 In my directory ./ I have an empty file Foo.hs and a shared object file
 mylib.so. From that directory in the shell,

     $ ghci Foo *.so
     GHCi, version 7.8.2: http://www.haskell.org/ghc/  :? for help
     Loading package ghc-prim ... linking ... done.
     Loading package integer-gmp ... linking ... done.
     Loading package base ... linking ... done.
     Loading object (dynamic) mylib.so ... failed.
     <command line>: user specified .o/.so/.DLL could not be loaded
 (mylib.so: cannot open shared object file: No such file or directory)
     Whilst trying to load:  (dynamic) mylib.so
     Additional directories searched: (none)

 It's interesting that GHCi searches ./ and identifies the correct object
 file, but then fails to load it. I have also tried the path ./*.so for the
 GHCi option.

 However, if I move mylib.so to a directory ./Temp,

     $ ghci Foo Temp/*.so

 loads without issue.
