New description:
Sage currently has workarounds against building an incompatible
libreadline on openSuSE 11.1 and Arch Linux - instead of building it, the
system version is copied.
The SuSE workaround should be applied to openSuSE 11.2 and 11.3, too.
Furthermore, SuSE offers libreadline.so.5 in addition to .so.6, so we only
copy .6.
The workaround on Arch Linux is unreliable, as it detects Arch Linux by
"-ARCH" in the kernel version (which is the default, but might be
different). Instead, the presence of /etc/arch-release should be used to
determine that.
I am attaching a patch that fixes those problems and changes 'cp' to 'cp
-a' to not turn a symlink into a file. Without this patch, sage fails to
build on my SuSE or Arch systems.

Comment:
See the description for a link to a p3 spkg with Thomas' patch. I'll
attach a Mercurial spkg patch shortly. Note: I have not tested the new
package. Please do this!
