Testing on Win32 checks out OK, but on Linux I see some errors, first off:

Am I doing something wrong here?  Is this due to the lib names not being 
mangled anymore?  If so can we please have a better error message :-)

And when I set ICU_PATH I see a different error:

Note that my Boost tree is actually located on a windows NTFS drive with 
\r\n line endings, could/should this effect things?

Thanks, John.
