+Summary: Profiling module loader hardcodes .so extension on Mac OS X
+Description of Problem:
+Profiling plug-ins are loaded with a hardcoded .so extension, but shared libraries on Mac OS X 
+carry a .dylib extension. This causes an attempt to load a profiling extension with eg --
+profile=desc-heap to fail unless the file is renamed or symlinked with a .so extension.
+Steps to reproduce the problem:
+1. Checkout heap-prof from SVN and install it
+2. Run some program with the profiling module:
+  mono --profile=heap-desc MWUpdateDaemon.exe
+Actual Results:
+ ** (MWUpdateDaemon.exe:6672): WARNING **: Error loading profiler module 'mono-profiler-
+desc-heap': dlopen(libmono-profiler-desc-heap.so, 9): image not found
+Expected Results:
+Should load the .dylib file and do profiling stuff.
+How often does this happen? 
+Every time.
+Additional Information:
+Mac OS X has both 'bundle' code files, which may have a .so extension, and 'shared libraries' 
+which carry the .dylib extension. A look in my mono/lib directory shows a number of files of both 
+types; it may not be totally clear which is the 'correct' type to use.
+Workaround: symlink the .dylib file to a .so extension.
