Ouch.  This may actually have a very high impact on developers at
least, if not others.

Suppose my project does something along the lines of the standard
NQP/Rakudo build process, with:

    $ perl Configure.pl --gen-parrot
    $ make
    $ make install

Then I later make some changes to dynops or dynpmcs and do

    $ make

This second make will end up locating the installed (out-of-date)
versions of the dynext libraries instead of the freshly compiled
ones in the current directory.  Yes, we can update environment
variables in the Makefile (how do we do this in Windows, ooc?),
but older releases of our project won't work with recent Parrots.

Also, is the current/default list of library paths available 
somewhere, either in documentation or easily displayable from 
the parrot command line?  I'm not at all clear what directories
are being searched.
