I haven't seen a reply on R-sig-debian, so please report back there
too if you make progress.

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

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 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.

In my experience, proj usually points to something related to proj4 -
are you sure that proj4 os properly installed, including dev files
(not sure if needed, but likely)?
