The URL www.yoctoproject.org/downloads/pseudo/pseudo-1.5.1.tar.bz2 does not point to the pseudo source. This appears to be a configuration issue on the web server. Either the server is fixed or the pseudo_1.5.1.bb in dora is fixed. The issue seems to exist in master as well.
Oops, I filed a bug without realising Holger had filed one already. Since Michael has been looking at that one I will mark this one as a duplicate of that. *** This bug has been marked as a duplicate of bug 6426 ***
