Some of our src rpms are affected because of a packaging issue. We are fixing them.

nss-devel is the only binary rpm which has this issue. We are working on it.

As a workaround, you can use "rpm2cpio <rpm> | /opt/freeware/bin/cpio -idmv" to extract it. This will extract files in the current directory. 

/opt/freeware/bin/cpio comes from cpio rpm.
