After adding the attached patch, I get the following error during compilation 
time of PerlQt:

I've checked the header for QPtrList, and it does define a *next() member at 
line 111 of qptrlist.h from Qt 3.3.8 with the following declaration:

    type *next()            { return (type *)QGList::next(); }

Ideas are welcome.
