One can also (partially) test the new patch by (optionally renaming the
Sage directory of an installation to be upgraded, then) running {{{./sage
-upgrade ...}}} with the ''current'' upgrade path, and '''after that'''
applying [http://trac.sagemath.org/sage_trac/raw-
attachment/ticket/9896/trac_9896
-fix_hardcoded_libdirs_in_extmod_linker_cmd-sagelib.patch the new patch]
to the Sage library, then running {{{./sage -ba}}} and {{{make
ptestlong}}} or alike. (Running just {{{./sage -b}}} would though show
that the obsolete hard-coded directory gets replaced, of course only if
{{{SAGE_ROOT}}} had been changed. Another way is to put fake directories
into {{{LDSHARED}}}, e.g. by setting it to {{{"gcc -bundle -L/foo/bar/
-undefined dynamic_lookup -Lbaz"}}} on MacOS X, or e.g. {{{"gcc -L/foo/bar
-pthread -Lbaz/ -shared"}}} on Linux.)
