cecile's problem may be related to this:

http://use.perl.org/~Qiang/journal/32464

I did notice (in relation to this) that Scalar::Util is not a core module in
perl 5.6.1, the minimal version we currently support.  We probably haven't had
any complaints since most users have perl versions > 5.8.  Looks like it was
added circa perl 5.7.3:

perl -MModule::CoreList -e 'print
Module::CoreList->first_release("Scalar::Util"),"\n"'
5.007003

We should consider either (1) adding this to the dependencies and continue
supporting perl 5.6.1, (2) supporting a min. version of 5.8 or above, or (3)
removing any use of weaken()/isweak().  I support either of the first two
choices; it's a valuable module to have around.
