  Ah, the message is confusing.  It is not cygxalan-c111.dll that cannot be
found, but a library to which it is linked that cannot be found, preventing
cygxalan-c111.dll from being loaded by Xalan.exe.

  Hmm, I don't know what ldd is doing, but I used cygcheck to take a look at it:

  So, it turns out there's a bug in the "make install" stage.  The missing
cygxalanMsg111.dll is built OK, but only the link library gets installed, not
the actual DLL itself.  You need to talk to upstream about this bug in their
makefile.  As a workaround, copying the DLL manually from the build directory
to whereever you've got the other DLL installed works fine.

    cheers,
