By local directory, do you mean local relative to the source file?

The 'so mode of `define-runtime-path' is intended to refer to libraries
in a PLT Scheme "lib" directory---usually adjacent to the binaries. If
you put the libraries in a "lib" relative to the source that uses them,
then you want just the relative path, perhaps using `(system-type
'so-suffix)' to build the path.


Meanwhile, an 'so path works anyway if the shared library exists
relative to the current directory, due to the way that the
shared-library search path works. Also, `mzc' looks strictly in the PLT
shared-library directories to resolve 'so, and it doesn't complain when
it fails to find a library. That's a confusing combination that we
should at least fix on the `mzc' side.
