If SRCTOP != BLDTOP, and SRCTOP is given in relative form, e.g. "./config ../openssl", then a bug in Perl's abs2rel may trigger that directory- rewriting in __cwd results in wrong entries in %directories under certain circumstances, e.g. when a test executes run(app(["openssl"]) after indir. There should not be any need to go to a higher directory from BLDDIR or SRCDIR, so it should be OK to use them in their absolute form, also resolving all possible symlinks, right from the start. Following the File::Spec::Functions bug description (reported to perl.org): When abs2rel gets a path argument with ..s that are crossing over the ..s trailing the base argument, the result is wrong. Example PATH: /home/goal/test/.. BASE: /home/goal/test/../../base Good result: ../goal Bad result: ../..
