Larceny supports both SLIB and R6RS.

I have both a number of R5RS implementations with SLIB, and a few R6RS
implementations installed at the same time; and this is not that rare.

SCHEME_LIBRARY_PATH in this SRFI only specifies where R6RS libraries
are. If R^NRS libraries (for some N > 6) will not be compatible, you'll
end up with the same kind of conflict.
