This should've been s/on every interpreter startup/on require time/, see #510895. However, some quick tests indicate the stat() calls are made anyway, and that this was the case for squeeze too. Not sure how much that matters though. Still, creating /usr/local/lib/perl/<version> from postinst scripts leads to a profileration of empty directories in the common case where CPAN is never used. I'd rather avoid that. > Possibly we need to make CPAN::FirstTime try to mkdir those directories > when probing. My current thinking is that a minimally invasive fix would be a loop that tests the first existing directory up the tree for writability. This way we can leave the mkdir part (along with umask settings, see debian/patches/debian/writable_site_dirs.diff) for later. > Help (and opinions on the right thing to do) is welcome on this.
