-----------------------------+----------------------------------------------
There are some problems with SAGE64 and sage-check-64. First, sage-
check-64 gets run whenever sage-env gets run, which is way too often. As
a consequence, if SAGE64 is set, I get extra messages printed whenever I
run anything like "sage -hg":
{{{
$ sage -hg status
Detected SAGE64 flag
Building Sage on OS X in 64-bit mode
}}}
This is annoying on its own, but it also produces incorrect information
when running "sage -pkg": the extra messages make hg think that there are
unchecked in changes.
Also, in several files in the scripts repo, comments say that SAGE64 is
only for use on OS X or Solaris, but there are no such distinctions in
various spkg-install files that I've looked at: if SAGE64 is set, then it
tries to build in 64-bit mode, regardless of the platform.
In contrast, the file sage-check-64 only prints messages about building
64-bit if on OS X or Solaris.
Finally, the script sage-check-64 creates a file
SAGE_LOCAL/lib/sage-64.txt if SAGE64 is set to "yes", to record the fact
that this is a 64-bit build. This makes sense if SAGE64 is unset, but if
the user sets SAGE64 to "no", then this file should be ignored, and in
fact deleted.
The attached patch gets rid of the distinction between OS X, Solaris, and
everything else. It deletes sage-64.txt if SAGE64 is "no". It also only
runs sage-check-64 from sage-spkg (which is what calls spkg-install) and
sage-build (which may not be strictly necessary, but it was there
already). It no longer runs it from sage-env.

I've asked some questions about this on [http://groups.google.com/group
/sage-devel/browse_thread/thread/42573acff76e26b0?tvc=2 sage-devel]. If
the answers are not what I expect, then this may need to be rethought.
