thanks for the suggestion, but I must be missing something: since
Hmisc imports survival (as well as Depends: on it), what can Hmisc
change to make the survival functionality visible to my package?

Well, as I said, things work fine if I leave Hmisc in the Depends:
field, which, however, is against CRAN policy. The trouble is that I
don't have a good way of checking whether something breaks by moving a
package from Depends into Imports...
