Problems with doing a 'make test' to install perl modules in to SciPDL

[karlglazebrook]

If you try compiling and installing your own perl module on top of SciPDL you will likely run in to this error with make test:

This is a feature unfortunately, because to notarise the distribution I need to harden the perl runtime and this precludes using relative paths as in make test. Hence the error 'relative path not allowed in hardened program)'.

Note make install will still work and then you can run the test script. Or you can do:

% perl  -I$(pwd)/blib/lib -I$(pwd)/blib/arch test.pl 
1..1
ok 1

If you are compiling lots of modules and this griefs you, you can permanently remove the hardening of the perl binary by resigning it generically like this:

xattr -d com.apple.quarantine /Applications/PDL/bin/perl
codesign -f -s -   /Applications/PDL/bin/perl

And then everything will just work as expected. Make sure you trust the perl binary!
