Try to make it work on opensolaris:

* SunOS basic regexps are very /basic/: no support for character classes like
  [:alnum:], no '+' (not even '\+') and the greediness of stuff like '\{m,n\}'
  is not well defined, which is a problem in sed 's/.../.../' (according to
  the man page, it should work only with regular expressions matching a single
  character, i.e. not with '\(...\)').  Therefore, a lot of parsers had to be
  rewritten, especially the one for (versioned) dependencies.
* Don't use grep's -q option, it's not portable.  Use >/dev/null instead.
* Awk on SunOS is very basic as well.

Currently it still fails in configure, but at least it gets there...
