We miss the method resolution to DynaLoader::bootstrap, the modules @ISA is not 
stored. 
This is also the underlying reason, why we use DynaLoader::bootstrap_inherit 
internally in dl_init.

Correction: It's not that the @BSD::Resource::ISA is not stored, the compiler 
does not know about it.

For now beware that you cannot lazy load modules which use DynaLoader and 
AutoLoader.

DynaLoader and AutoLoader packages: 
core: IPC::SysV DB_File
cpan: Net::LibIDN Net::SSLeay BSD::Resource

Reproducable with cpanel perl with: BSD::Resource  IPC::SysV
Not repro on other systems (macosx, linux)

Other errors: Missing %Config at Errno.pm: Net::SSLeay Net::LibIDN

The @ISA related problem is fixed now in branch dl-308, tested ok on all cpanel 
and normal perl 5.14.

Missing %Config at Errno.pm in run-time loaded Net::SSLeay Net::LibIDN (and 
probably more) in a seperate ticket
