Thanks, pryrt. It does indeed help to know that a similar setup has been shown to work in that I know it isn't a complete non-starter. Both the perl and gpg binaries are 64bit and I'm using Linux on a physical host (although if I can get this working it will go on VMs in production).

Will keep plugging away at it and report back if I get anywhere.

Update: It appears to be dependent on the key size. A valid signature is produced from a 1024 bit key but not a 4096 bit key (which I tend to use by default these days).

Update 2: It's more complicated than that. It only works with some 1024 bit keys. I'm beginning to think that maybe this module isn't suitable for production environments after all. :-/
