Comment(by vbraun):
It would be nice if a shell function `newest_version()` would also be
available for other spkg to check that required versions of dependencies
are available. So I'd like it to be in 3rd file `install-functions` (or
so) that is sourced by `install`. Perhaps with a better name, for example
`requires_version(mpir,1,1,2)`...
Moreover, the current `newest_version` script does not check that it is
called from `$SAGE_ROOT/spkg`. If it is called from the wrong directory, I
get
{{{
/home/vbraun/Sage/sage/spkg/standard
[vbraun@volker-two standard]$ ./newest_version mpir
mpir-1.2.2.p2
}}}
on Linux and
{{{
vbraun@t2:standard$ pwd
/home/vbraun/t2/sage-4.6.1-sunos-32bit-5.10-sun4v-SunOS/spkg/standard
vbraun@t2:standard$ ./newest_version mpir
}}}
(no output) on t2/Solaris.
