objdump: dknisxxxxx.o: File format not recognized
Then that's your problem ... or at least *one* problem that needs to be fixed.
Could that libperl516.a that's being found be a 32-bit version of libperl516.a ? The error messages from objdump would fit such a scenario.
Compare it to the libperl516.a that's on the other machine you mentioned. They should be identical (obviously), right down to the Digest::MD5 signatures, if they're the same builds of Strawberry Perl.
Afterthought: If that libperl516.a is 64-bit, then another possibility is that you've just run a 32-bit version of objdump on it. That would also fit the objdump errors you reported.
