For systems with a missing or broken perl, it is nicer to explicitly say "we don't want perl" because: 1. The Makefile knows not to bother with Perl-ish things like Git.pm. 2. We can print a more user-friendly error message than "foo is not a git command" or whatever the broken perl might barf 3. Test scripts that require perl can mark themselves and such and be skipped This patch implements parts (1) and (2). The perl/ subdirectory is skipped entirely, gitweb is not built, and any git commands which rely on perl will print a human-readable message and exit with an error code. This patch is based on one from Robin H. Johnson. Signed-off-by: Jeff King <peff@xxxxxxxx> --- This is a rebase of what I sent earlier (the original was based on 1.6.2.1).
