Thanks Roger; I tried reinstalling rgdal, and got some more clues
following install.packages("rgdal") (relevant lines only):

---<--------------------cut here---------------start------------------->---

and:

in addition to the error I previously reported.  So AFAICS, it seems
like a problem with Debian sid's libgdal1-1.7.0 or one of the libdap
packages, given the "undefined reference to
'libdap::AISConnect::AISConnect(std::basic_string<char,
std::char_traits<char>, std::allocator<char> > const&)' line.
