Line 8 of dep/pcre.mk attempts to download using https, which the site referred to does not allow. Replacing “https” with “ftp” so that the line reads
$(JLDOWNLOAD) $@ ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre2-$(PCRE_VER).tar.bz2
will solve the problem. I saw that the file in julia master links to a different site. I don’t see how to make a PR for the 0.6.2 release…
