Of course, that won't work if SqueakFFIPrims.so isn't in the current
directory.

My dlopen() manpage says that you either need an absolute pathname, or
a name like "lib<name>.so[.xx[.yy]]" for a DSO to be found. I don't think
dlopen() will find SqueakFFIPrims.so in the normal library search path.

BTW, the latest (2.8pre4) source builds all the plugins with libFoo.so.0.0
style names.
