Part of the problem is that I didn't get any informative error. :(

Yes.

But I didn't change the perl version, only the PDL version. I was in
the process of rebuilding/testing/installing Photonic.

I got the errors when Build-testing the Photonic
package. Unfortunately, the only error message I got was that the
planned number of tests were not run. I tried 'proving' individually
the test programs (i.e., prove t/...; prove -v t/...) but they
messages were not much more informative. I tried running the tests
directly (perl t/...) but it gave me a segmentation fault.
So maybe I can rephrase my question in a more general way: how do you
debug test programs (programs that use Test::More) to find out
why they fail.

Luis
