in particular this problem: ---------- In file included from /usr/lib/perl5/5.14/x86_64-cygwin-threads/CORE/op.h:653:0, from /usr/lib/perl5/5.14/x86_64-cygwin-threads/CORE/perl.h:3450, from Detective.xs:38: /usr/lib/perl5/5.14/x86_64-cygwin-threads/CORE/reentr.h:109:26: fatal error: crypt.h: No such file or directory # include <crypt.h> ^ compilation terminated. Makefile:335: recipe for target 'Detective.o' failed make: *** [Detective.o] Error 1 ----------- looks like a broken test machine to me, I don't think this is fixable at my end. What do you think?
