Re: Re: kde-sunset: new akode build problems

Hey thanks! This fixes it, but I'm not sure how to fix it properly. A
simple solution is to just call libtool directly (everyone should have
it installed), but I don't think it's right:

I just tried it and make file with error:
kangaroo lib # make
make  all-am
make[1]: Entering directory
`/var/tmp/portage/media-libs/akode-2.0.2/work/akode-2.0.2/akode/lib'
/bin/sh libtool --silent --tag=CXX --mode=link i686-pc-linux-gnu-g++

This is correct, those files does not exist, since I don't have gcc
4.4.3 installed (had it once, now I have 4.4.4). I tried gcc-config
and it still throws this error. After rebuilding libtool, it worked
like a charm. So this leads me to think that gcc version is somehow
hardcoded in libtool? But that's just stupid, it can't be.

Do you have any suggestions?
