Hi,

for Sage 3.3.alpha3 I got a strange build failure with the new
cddlib-094f.spkg on my Intel Core2Duo MacBook / Mac OS X 10.4.11,
XCode 2.5:

The make run (acually MAKE='make -j2' ) won't extract this spkg (see
log posted below).
After changing the name to "cddlib-04f.tar.bz2", unpacking it (by
double-cklicking), and then repacking it with:

sage -pkg cddlib-094f

(where the "sage" command is the sage3.3.alpha3 from the incomplete
install ...) I get a new spkg which is fine for the build process.
Weird. Another MAKE now made the build continue (still running).
It seems to be some deficiency of the "tar" of my system (Mac OS X
10.4.11), "tar --version" gives:

tar (GNU tar) 1.14 +CVE-2006-0300 +CVE-2006-6097

Modified to support extended attributes.

The log output with the failure in question follows below; the
original tar file seems to contain "obsolescent base-64 headers".
Is that worth a trac ticket?

Cheers,
gsw
