[gentoo-science] Locating ar

[Thomas Kahle]

Hi,

I'm constantly failing at a rewrite of the ebuild for
sci-math/singular to bump it to 4.0.0.  (Current version
attached).  Singular has its own malloc implementation called
omalloc.  The configure script there can't find ar if run from
within portage context.  It does find it when run on a normal
shell.  I tried tc-export AR to no avail.  Any ideas?

Cheers,
Thomas
