Bill,

Please see #601977 and let me know if you still feel the same way.

Basically, the dependency from cyrus-sasl2-dbg is on
"cyrus-sasl2-mit-dbg | cyrus-sasl2-heimdal-dbg", while the two specific
-dbg packages depend on the main package.  Basically, if a user
installs the cyrus-sasl2-dbg, we want them to also get the specific
symbols for one of MIT or Heimdal.  This also takes care of a bug in the
Lenny -> Squeeze upgrade process (reported in #601977).  However, if the
user goes the route of installing either cyrus-sasl2-mit-dbg or
cyrus-sasl2-heimdal-dbg, then we also need to make sure that they get
the common -dbg symbols.

Regards,

-Roberto
