Yes, aptitude can do that. Quoting the manual[1]:
,----
| ?provides(pattern), ~Ppattern
|
| Matches package versions which provide a package that matches the
| pattern. For instance, “?provides(mail-transport-agent)” will match
| all the packages that provide “mail-transport-agent”.
`----
In the current case, "aptitude search '~Plsb-base'" does the trick.
