See lots of discussion at [https://groups.google.com/forum/#!topic/sage-
release/6Vh55hF7UXk this sage-release thread]. Best guesses are either
[https://github.com/wbhart/flint2/issues/55 this Flint bug] and leif's
idea that there is a missing linker flag on Darwin (see the sage-release
thread).
----
This is not eclib's fault, but due to incomplete / wrong "`install_name`s"
(meant to be ''absolute'' paths) in libflint.dylib (and also libpari-
gmp.dylib).
On Darwin 10 (MacOS X 10.6) and later, apparently the linker is smarter
(or more tolerant), and does find the indirectly used libraries in
`$SAGE_LOCAL/lib/`, despite their wrong `install_name`s.
