Are you installing to ram? Maybe that is a factor, I used the conventional tcz way, mounting..
Edit: Well, how nice. GNU cpio as in 2.4rc4 segfaults when loading libgsf to ram.
GNU cpio is no longer used, but it should be checked with busybox cpio. And also if it's because of cpio, or the script.
edit 2. Busybox cpio is more verbose about it: short read, I/O error. The libgsf extension is corrupted, and the corruption is in the dev headers, that's why abiword runs when mounted.
