 Hi David,
 I would advocate a simple check as you mention above, but with an error
 that points to a paragraph on the pkgsrc guide (to be added) that
 describes the objdir limitation.  I stumbled upon this, so other users
 may in the future as well.
 
 That said, I've changed my objdir, so if such a check is not going to be
 added for whatever reason, somebody can close pkg/45450.
 
 Regards,
 John
