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

/usr/lib/libgdal1.7.0.so: undefined reference to `libdap::AISConnect::AISConnect(std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)'
collect2: ld returned 1 exit status
./configure: line 3366: ./proj_conf_test: No such file or directory
PROJ.4 Version 4.7 or earlier
/usr/lib/libgdal1.7.0.so: undefined reference to `libdap::AISConnect::AISConnect(std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)'
collect2: ld returned 1 exit status
./configure: line 3409: ./proj_conf_test: No such file or directory
/usr/lib/libgdal1.7.0.so: undefined reference to `libdap::AISConnect::AISConnect(std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)'
collect2: ld returned 1 exit status
./configure: line 3459: ./proj_conf_test: No such file or directory

and:

/usr/lib/libgdal1.7.0.so: undefined reference to `libdap::AISConnect::AISConnect(std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)'
collect2: ld returned 1 exit status
./configure: line 3366: ./proj_conf_test: No such file or directory
PROJ.4 Version 4.7 or earlier
/usr/lib/libgdal1.7.0.so: undefined reference to `libdap::AISConnect::AISConnect(std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)'
collect2: ld returned 1 exit status
./configure: line 3409: ./proj_conf_test: No such file or directory
/usr/lib/libgdal1.7.0.so: undefined reference to `libdap::AISConnect::AISConnect(std::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)'
collect2: ld returned 1 exit status
./configure: line 3459: ./proj_conf_test: No such file or directory

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.

Cheers,
