If you are looking to learn Catalyst, then your first step should be the excellent Catalyst::Manual::Tutorial. If you do the whole thing including the exercises then you will learn a lot.

In addition, depending on what you are doing, it might be wise to do some extra study on DBIx::Class and TT2. There are Tutorals and exercise available for them as well.

I have experienced any problems with PERL_DL_NONLAZY. Have you tried google?
