To jeszcze kloczek dodał; nie pamiętam, po co zmieniałem nazwę...

  There is also an potential problem with the shared perl library if you
  want to have more than one "flavor" of the same version of perl (e.g.
  with and without -DDEBUGGING).  For example, suppose you build and
  install a standard Perl 5.8.0 with a shared library.  Then, suppose
  you try to build Perl 5.8.0 with -DDEBUGGING enabled, but everything
  else the same, including all the installation directories.  How can
  you ensure that your newly built perl will link with your newly built
  libperl.so.8 rather with the installed libperl.so.8?  The answer
  is that you might not be able to.  The installation directory is
  encoded in the perl binary with the LD_RUN_PATH environment variable
  (or equivalent ld command-line option).  On Solaris, you can override
  that with LD_LIBRARY_PATH; on Linux, you can only override at runtime
                             ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  via LD_PRELOAD, specifying the exact filename you wish to be used;
  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  and on Digital Unix, you can override LD_LIBRARY_PATH by setting the
  _RLD_ROOT environment variable to point to the perl build directory.

Zgodnie z moimi testami, to nie jest prawdą; LD_LIBRARY_PATH jak
najbardziej działa.  Do wywalenia, nie?
