fix bug
Revert "add README.md"

This reverts commit fbb5f1e9784832a7ff335f9b4fcfbe5314462e0d.
Improve bundled library check.

IMP DSOs should not be linking to any library (other than other parts of
IMP or RMF) in /usr/local/lib/. Such libraries (installed by homebrew)
typically won't exist on the user's machine.
Use the name that was linked against.
Add missing bundled library.
echo no longer accepts (or needs) the -e option.
Make sure we don't use the echo builtin.
Skip trying to parse examples.
