EDM on OS X gets access fault in ipAddrToAsciiEngine::allocate

[Eric Norum]

Compile and build latest edm/base on OS X/Intel
Trying to run EDM gets access fault in ipAddrToAsciiEngine::allocate

Here's the stack trace:

The guard class mutex is being used before it has been created.

Additional information:
A quick workaround was to add libCom before the EDM libraries in the EDM makefile:

This is a quick hack and not a real fix, though!
I'll leave a *real* fix up to the C++ experts.

I wonder if this is an issue only with a static build or if it occurs also when using shareable libraries?
