I can't find mscvr71.dll (or msvcr71.dll) anywhere within my Visual
Studio 6 or Visual Studio 7 (.NET) installations. Where is that dll
located on the box that has it ? (Also please verify that the name is
correct.) In general, afaik, the compilers themselves contain very few
dll's.

In my experience this is never a problem. I have binaries built with
MSVC++ 6 working quite happily on a perl built using the gcc compiler -
and vice versa.
And the binaries that ActiveState provide generally end up on machines
that don't have any compiler at all.
I would expect those very same binaries to work with a perl that was
built with Visual Studio 7. (I've verified that the AS binaries work
with gcc-built perl, but *not* that they work with VS7-built perl.
Perhaps there are issues I'm unaware of.)
The key to building binaries is to use the same compiler that was used
to build perl. If your perl was built with VS 6, then use VS 6 to build
the binaries. Do that and I would expect those binaries to work with a
perl built with VS 7, or a perl built with gcc, or a perl built with
Borland.
If your perl was built with VS 7, then use VS 7 to build the binaries.
Do that and I would expect those binaries to work with a perl built with
VS 6, or a perl built with gcc, or a perl built with Borland.
Where you will get into trouble (and I suspect this is where you have
come undone) is if, for example, you build your Win32 module binaries
using a perl that was built with VS 6, but you use the VS 7 compiler.
Hope there's something there that helps.
I could actually send you binaries of Win32 built using Visual Studio 6,
Visual Studio 7, or gcc (if that helps). I would expect each of those
binaries to work eaqually well on your perl (irrespective of what was
used to build your perl). And if my expectation was incorrect in any
way, then we'd both learn something :-)
Cheers,
Rob
