Paludis picks up the wrong USE flag with -E portage

[chutz]

Paludis with -E portage is trying to install gcc with USE=fortran. The only way to get around it is to specify "sys-devel/gcc -fortran" in /etc/portage/package.use.

I have both paludis and portage installed.

I have:

USE="... -fortran ..."

in /etc/make.conf

*/* ... -fortran ...

in /etc/paludis/use.conf

I don't have anything else mentioning "fortran" in the above two files or /etc/portage/package.use

# emerge -pv gcc

Please attach complete Portage configs.

Attached /etc/make.conf and here is the simplified portage configuration for this testcase:

possum ~ # eselect profile show
Current make.profile symlink:

Hrm. Does this fix it?

Replying to ciaranm:

Thanks for the effort, Ciaran, but it did not make any difference. :(

Fairly sure that works.
