Hi,
when I try to cross compile sys-fs/e2fsprogs I get this error:
checking for blkid_get_cache in -lblkid... no

copying the uuid and blkid files to the cross environment solve the problem
and the package compiles.
cp /tmp/target_root/usr/lib/libuuid.* /usr/i686-gentoo-linux-gnu/usr/lib/
cp /tmp/target_root/usr/lib/libblkid.* /usr/i686-gentoo-linux-gnu/usr/lib/
cp /tmp/target_root/lib/libuuid.so.1*  /usr/i686-gentoo-linux-gnu/lib/
cp /tmp/target_root/lib/libblkid.so.1*  /usr/i686-gentoo-linux-gnu/lib/

How can this problem be solved permanently?

Regards,
Kfir
