Too old for what? Not Mapnik 0.7.0, which again works with ubuntu- 
repository boost and icu. If it did not them please give me details.

Ya, don't do that :)

The problem now is that libboost_regex is linked against the /usr/lib  
icu.

The way to test this is to run:

$ ldd /usr/local/libboost_regex.so

which will likely should linking against the /usr/lib icu.

...so you need to rebuild it to link to the /usr/local/lib icu. This  
can be very hard because the bjam tools don't tend to work right with  
two versions of icu and tend to end up linking to /usr/lib even if you  
correctly pass the -s options like this:

sudo ./bjam  --with-regex toolset=gcc -sHAVE_ICU=1 -sICU_PATH=/usr/ 
local -a install

So, what you may have to do is move the /usr/lib/libicu out of the way  
temporarily while you re-compile boost_regex. Or just follow my advice  
above and rollback to using the apt installed boost and icu.

Or... lastly, recompile boost_regex with -sHAVE_ICU=0 to avoid the use  
of ICU altogether.
