Why can't I run dbx?
The development environment is a separate layered product beyond the base OS.
Although it is included on the Digital UNIX consolidated CD-ROM, the license
must be purchased separately to use any portion of the Developer kit. Within
the Digital UNIX Developer Kit the license just happens to be enforced by a
check in dbx.
