Our module is passing tests on all of the 32-bit ActiveState test servers, and passing on the 64-bit Perl V5.12 test server, but it's failing on both Perl V5.14 and V5.16 64-bit.
The root cause appears to be an XS/Perl mismatch for Win32::API. Here's the relevant snippets from your build logs:
From your build of our module on 64 bit Perl V5.14:
Win32::API object version 0.62 does not match $Win32::API::VERSION 0.63 at C:/Perl64-5.14/lib/DynaLoader.pm line 214.
And, from your build of our module on 64 bit Perl V5.16:
Win32::API object version 0.73 does not match $Win32::API::VERSION 0.75 at C:/Perl64-5.16/lib/DynaLoader.pm line 214.
We're not explictly calling out Win32::API as a prerequisite. We do mark Win32::SerialPort as a prereq, which is what is pulling in Win32::API. Other than that, we're not doing anything in our Build.PL or Makefile.PL (that I can see) that would trigger this sort of problem.
On the other hand, I see other modules that use Win32::API building just fine. Not sure if it's just a "luck of the draw" thing where their tests land on a different server, or if we're doing something wrong in our packaging, build scripts, etc.
Does this look to be an issue with the test servers, or something we're doing wrong?
