I mostly operate from the command line, so all the installation was
done from a macosx bash shell. tar is GNU tar version 1.14.
I downloaded sage-2.1.13-osx10.4-i386-Darwin.tar.gz from sagemath.org/
SAGEbin/apple_osx/intel
md5 checksum is OK
tar -zxf sage-2.1.13-osx10.4-i386-Darwin.tar.gz
fails with the same error...
tar: sage-2.8.13-i386-Darwin/local/LIB: Cannot create symlink
to `lib': File exists
So I tried
tar -ztf sage-2.1.13-osx10.4-i386-Darwin.tar.gz > tarlist
and then grepping for 'tar: sage-2.8.13-i386-Darwin/local/LIB' and for
tar: sage-2.8.13-i386-Darwin/local/lib
This shows that both LIB and lib directories exist in the tar listing.
The lib directory and contents is put down first, then what I assume
is a symbolic link is created from LIB to lib - but I'm not sure.
the /local/LIB file/link does not exist in the PowerPC version
Could this be something to do with case-insensitivity in the default
MacOSX filesystem? All my drives are formatted to Mac OS Extended
(Journaled), which would not differentiate between LIB and lib. Trying
to create a symbolic link from LIB to lib would effectively be
creating a link to itself. Possibly, if the build was only tested on a
case-sensitive disk, this would not show up in testing. Or maybe the
LIB link is unused, so the PowerPC version does OK without it, but in
the Intel version it is causing the untar'ing to fail.
