thanks to kit baum there is an update of -psmatch2- available from ssc.
this update repairs a bug that arose in the context of matching without
replacement.
the update required a recompile of the plugin. at the moment ssc
provides a version for linux and windows only (the platforms that i can
compile for).
people who spend their days on a different os, and who want to use
-psmatch2-, can contact me off-list for the source code of the plugin so
that they can compile it themselves.
