happy - if you guys can agree on what I should try, I don't have infinite
time with that machine ;-)
There are plenty of things you ''could'' try... :-)
But I think kiwifb and me agree on that you could first try to:
* Restore `module_list.py` (at least remove `flint`, optionally also
`pari`) from the "needed" libraries of the libs.mwrank Python extension
module -- to test whether it works for ''one of'' the affected modules
(you had to change about five IIRC)
* Make sure libflint's `install_name` is still just `libflint.dylib`
(otherwise `install_name_tool` will give an error):
{{{
#!sh
$ cd $SAGE_ROOT
$ otool -D local/lib/libflint.dylib
local/lib/libflint.dylib:
libflint.dylib
}}}
* Change the `install_name` (here called "id") to the library's absolute
path:
{{{
#!sh
$ install_name_tool -id `pwd`/local/lib/libflint.dylib
local/lib/libflint.dylib
}}}
* Then either rebuild/reinstall eclib (which should now record libflint's
absolute path), or -- simpler -- just change the recorded name (for FLINT)
in `libec.0.dylib` manually:
{{{
#!sh
$ otool -L local/lib/libec.0.dylib # just to check libflint's name there
local/lib/libec.0.dylib:
<path to>/sage-6.2.beta5/local/lib/libec.0.dylib (compatibility
version 1.0.0, current version 1.0.0)
libflint.dylib (compatibility version 0.0.0, current version
0.0.0)
...
$ install_name_tool -change libflint.dylib `pwd`/local/lib/libflint.dylib
local/lib/libec.0.dylib # now really change the name
$ otool -L local/lib/libec.0.dylib # just to verify it changed
local/lib/libec.0.dylib:
<path to>/sage-6.2.beta5/local/lib/libec.0.dylib (compatibility
version 1.0.0, current version 1.0.0)
<path to>/sage-6.2.beta5/local/lib/libflint.dylib (compatibility
version 0.0.0, current version 0.0.0)
...
}}}
* Pretend file modification to trigger the rebuild of the module(s):
{{{
#!sh
$ touch src/sage/libs/mwrank/mwrank.pyx # and more if you like
$ ./sage -b # and now rebuild
}}}
The linker should now be able to locate `libflint.dylib` referenced by
`libec.dylib`.

Optionally, repeat the steps analogously for `pari` (which in contrast is
originally listed as a needed lib in `module_list.py`, so you'd have to
really remove it rather than restoring the state of vanilla beta4 or
beta5); just libpari's original `install_name` is a bit more complicated
(with a non-existing temporary path):
{{{
#!sh
$ otool -D local/lib/libpari-gmp.dylib
local/lib/libpari-gmp.dylib:
<path
to>/sage-6.2.beta5/local/var/tmp/sage/build/pari-2.5.5b.p1/src/Odarwin-i386
/libpari-gmp.dylib
}}}
(`libpari.dylib` is a symbolic link to `libpari-gmp.dylib`.)
When you change the name (again in `libec.0.dylib`), you have to specify
the '''full original (invalid) path''':
{{{
#!sh
$ install_name_tool -change
/Users/leif/Sage/sage-6.2.beta5/local/var/tmp/sage/build/pari-2.5.5b.p1/src/Odarwin-i386
/libpari-gmp.dylib `pwd`/local/lib/libpari-gmp.dylib
local/lib/libec.0.dylib
}}}
(Just as an example -- note that the invalid path will differ on a
PowerPC, and of course your `$SAGE_ROOT`.)
