Perl ldflags - packaging bug, upstream bug, or weird feature?

$ fgrep -- '-L/usr/local/lib' /usr/lib/perl5/5.8/cygwin/Config_heavy.pl
lddlflags=' -s -L/usr/local/lib'
ldflags=' -s -L/usr/local/lib'
ldflags_nolargefiles=' -s -L/usr/local/lib'
The above shows the presence of -L/usr/local/lib in the packaged perl
installation config vars.
This is a problem, because when compiling Perl extensions, it places
/usr/local/lib at the front of the library search path, taking precedence
over any other paths that the Makefile.PL may take care to specify. This is
bad, because /usr/local/lib may contain old/incorrect versions of libraries
which get found instead of the libraries the Makefile.PL attempted to point
to with explicit -L options.
I don't know enough about the perl build process to know where that option
is coming from - I'm hoping someone can tell me whether the presence of
those harmful -L/usr/local/lib options is a packaging bug, an upstream bug,
or a weird feature.
Max.
