In case anyone's interested, I resolved this (under springmeyers
tutelage) in the following way: I switched to Mapnik 0.7 which doesn't
require boost-regex be built with ICU. I rebuilt regex-boost
explicitly without ICU (by temporarily moving
/usr/local/include/unicode to /tmp). I then built mapnik 0.7 as per
the usual instructions.
I hit another bump after this when running "import mapnik" in the
python shell (I include the solution here in case it's related to the
above -- it may not be relevant for you): "ImportError:
/usr/local/lib/libmapnik.so.0.7: undefined symbol:
_ZN6icu_4313UnicodeStringD1Ev".
This was resolved (again by springmeyer) by patching SConstruct with this:
