# Eit. Getting perl to compile outside of the source tree is a severe pain.
# I got some of it working, but it's pretty bothersome, so we'll cheat here and

# Eit again.
# There's no easy way (well I don't see one, offhand) to sneak $(DSTROOT) into the
# location variables at "make install" time because make doesn't do the install.
# So we create config.sh, and then do a string replace for the install locations
# in there, which are meant for AFS, or we'd have configure options for it maybe.
# But we don't, so we hack some more.

# Triple eit.
# Having whacked values in config.sh effects Config.pm, and we don't want $(DSTROOT) in there.
# So we need to undo the damage once it is installed.

# Quad-eit:
# We may be building perl fat here, but a system may only have thin libraries installed.
# So now we need to remove the -arch build flags from Config.pm so you can build modules
# on those systems.  This means modules are build thin by default.
