Comment (by bardeau):

 Replying to [comment:2 ryandesign]:
 > If you don't care about portability, you can add a dependency on
 port:coreutils and use `${prefix}/bin/gsort` instead of `sort`. It does
 support `-V`.

 What is the proper way to to invoke gsort from my shell script? Is
 ${prefix} supposed to be a valid environment variable? It does not seem:
 {{{
 /opt/local/var/macports/build/_opt_local_var_macports_sources_github
 .com_macports_macports-ports_science_gildas/gildas/work/gildas-src-
 jun20b/admin/define-system.sh: line 28: /bin/gsort: No such file or
 directory
 }}}
 Isn't there a configure.* keyword I could use for reinplacement?


 > [https://stackoverflow.com/questions/4023830/how-to-compare-two-strings-
 in-dot-separated-version-format-in-bash There are many other potential
 solutions to this problem] of varying portability and correctness. I
 haven't tried them myself but maybe you'll see a method in there that you
 like.
 I precisely used one of the method proposed on this page (verle-verlt). A
 lot of methods contain bashisms which are not portable (in particular to
 dash or zsh). The verlt-verle is the softest solution I could find, at the
 cost of depending on a sort -V implementation.
