A heads-up: I'm afraid the random-effects probit "plugin" (loabable
module) got broken in the gretl 2019a release for Mac OS X. Thanks
to Jeff Bowman for pointing this out. The problem is fixed in the
current gretl snapshot for Mac.
The problem is obvious if you try to use random-effects probit: you
get an error message saying the plugin can't be loaded. The reason
for this is that the plugin was still linked against the previous,
out-of-date, version of libgretl. Only the one plugin is affected.
Note to self: be sure to do "make clean" before building gretl for a
release!
