[gentoo-user] using icc with portage

[Stefan G. Weichinger]

Anyone else using Intel's compiler, icc?

I do for quite a while now.
Followed http://www.gentoo-wiki.info/HOWTO_ICC_and_Portage

I still prefer gcc over icc so I use

http://www.gentoo-wiki.info/HOWTO_ICC_and_Portage#.2Fetc.2Fportage.2Fbashrc

to only use icc for stuff I list in /etc/portage/package.icc

Lately I get compilation-errors for packages that aren't listed in that
file, for example dev-python/numpy-1.6.1

It fails with log-lines telling me that icc was used to (try to) compile it:

[..]

# grep numpy /etc/portage/*

The shell is bash:

# echo $SHELL
/bin/bash

hmm

Yeah, I know, I could simply get rid of icc again.

But maybe someone in here has an idea why this fails.
Maybe it somehow needs some small fix somewhere.
