st: Re: moremata on the Mac

[Kit Baum <baum@bc.edu>]

This is not a Mata programming issue. It is a matter of accessing the  
right object libraries of Mata routines, which is something that  
Stata is supposed to do automatically. Similar problems have been  
discussed regarding David Roodman's -xtabond2-: someone installs a  
new version that has a new feature, and it does not work for them  
immediately after installation. If you quit Stata and restart, your  
first invocation of a Mata routine will rebuild the library list. You  
can use the 'mata mlib index' command to make that happen on the fly.  
But exiting Stata and starting a new Stata session will always deal  
with the problem.

This happens with official Stata as well, as the first libraries to  
be searched are the official Mata libraries:

You don't usually see the problem there, though, as when you update  
official Stata you often update the executable, and swapping  
executables will have the same effect as exiting and restarting Stata.
