Isn't version 2.3 in the beta zip?

No! MP does not call mpto etc. The reason for this is that (1) this process
is too sensitive for problems and (2) some of those tools are sensitive for
long lines and so (3) etc etc

This is why texexec does the calls after some cleaning up and check. It
also makes sure that it uses a temp file that does not clash.

You can look into texexec [search for doRunMP or ######] and add lines like 

print "IT WORKS TILL HERE\n" ; 

inside conditionals to check if you come that far. 

Also, say texexec --verbose to get an idea of what the settings are. Can be
helpful.
