True -- however, there is the nodeballs/ecore directory. Therefore, the install becomes:

make realclean
perl Makefile.PL
make
make install
cd nodeballs/ecore
../../bin/nbmasta install . everything

Hope this helps. There are a few other gotchas involved with getting Everything working under Perl 5.6 that you might want to keep an eye out for. First off, mod_perl and Expat don't play nice with each other. Secondly, Perl 5.6 requires jumping through a few more hoops to get inheritance working (patches here or here). I seem to remember that ther emight be one or two more, but these are the only two that bit me. Well, besides the premissions bug, which I think has been fixed in the most recent release. Anyways, hope this helps.
