Sigh.  While the basename is all we need to test if a DLL is already
loaded, it's *not* enough to load a DLL which still needs loading, if
the DLLs are not in the DLL search path, as in the case of Perl libs.
I'm going to generate a new 2012-02-09 snapshot right now.  Should be
up in 10 minutes or so.


Thanks for the report,
