IcedTea Bootstrap Process

This was very helpful since I ran into this problem and struggled until I
came back here.

I have made some pretty good progress (I think) on building IcedTea6 using
Apple's Java 5.  I have 'grep'ed all over and cannot figure out where this
error message is coming from.

Somewhere it does not know that the shared libs end in .dylib.  The
directory in question has:
Xusage.txt
libjsig.dylib
libjvm.dylib

I was able to get past this step by make sym links to of libjvm.dylib to
libjvm.so.

Any pointers is appreciated.
