Hm. I have noticed that LoadExternals does not return false on failure and
true on succeed. Rather, it is a fatal error if it fails, and returns
nothing on succeed; so checking the return value grants you nothing.
Now, I know nothing about Butler.XFCN, but this seems to work for me
("work" meaning it is obviously using the XFCN):
#!perl -wl
MacPerl::LoadExternals('Butler.XFCN');
print DBConnectInfo();
It prints "Invalid session ID" for me, so I know it is working at least
minimally, that MacPerl is loading the XFCN, and can run at least part of
it.
On another note, I wish I had known about this sooner; it would have been
nice to mention in the book that you can access a SQL database this easily
with MacPerl (even though it is only the one SQL database). Oh well. :-)
Hope this helps,
