The two may be compatible at the Perl source level, for the most 
part[*], but I doubt they're binary compatible.  A lot of Perl modules 
contain parts compiled from C and linked into the interpreter 
dynamically at need.

Unless you can mix these modules, I don't think you can expect Cygwin to 
consider ActiveState's distribution compatible.  If a Cygwin package 
needs Perl, it's fair for setup.exe to demand a Cygwinnish Perl to 
support it.  For all setup.exe knows, it's an absolute requirement.

[*] I also doubt they're 100% compatible at the source level, what with 
the various extensions each could be enabling that the other doesn't.
