Well I was using the env argument to system2, which claims to be
cross-platform (at least for R and make).  This command:

R_LIBS=/Users/hadley/R-dev R CMD INSTALL aL3xa-rapport-08e68ca/

is ok, isn't it?

My understanding (from reading R CMD INSTALL --help) was that
--library was for specifying the destination library.  Here I want to
specify the full libpath - i.e. some of the packages that this package
depends on may be in library 1, others may be in library 2.  Have I
misunderstood the documentation?
