> Wouldn't it be easier for upgrading to see if libpari-gmp.dylib exists,
and if so, delete it and then link libpari-gmp-2.4.dylib to it?
I was thinking of fixing this in general, not a specific work-around
limited to updating to ''this'' release.
> By the way, on a linux box I see libpari-gmp.so.2 and libpari-
gmp.so.2.3.5 lying around from the old install. They don't seem to cause
any trouble, but should they be removed also?
As I said, on Linux we seem to have the correct order of library search
dirs, so if all necessary files actually get rebuilt, the old libs
shouldn't cause problems. In fact, you can use both versions "at the same
time" (on Linux), i.e. some Sage modules using the old, and some the new
version. The Darwin loader doesn't support this, at least with how the
modules are currently built on Darwin.
For the directory renaming issue (perhaps typical for upgrades, but not
limited to):
{{{
#!python
distutils.sysconfig.get_config_vars()["LDFLAGS"]="" # remove potentially
obsolete "-L$SAGE_LOCAL/lib"
}}}
(To be added to {{{devel/sage/setup.py}}}; doesn't hurt on normal
installations where it is redundant anyway.)
