The above message contained the following:

Rats!  I was hoping it was something simple like that -- but you're too
good.  :-)

Good.  In general, the same compiler should be used for the extension
modules as was used for the perl utility.

> The symbol "Vdetach" is evidently the problem;

I agree.  Judging from your error message, that symbol is referenced by
your file "perl/blib/arch/auto/NetCDF/NetCDF.so" -- but not by mine:

    $ nm -g blib/arch/auto/NetCDF/NetCDF.so | grep Vdetach
    $

If I'm right, then why would your's reference "Vdetatch" but not mine?
