Trouble compiling regexpp example

Hi everyone.

I'm using the libboost-regex Debian package and I'm trying to compile 
one of the example programs, regex_match_example.cpp.

I am compiling with the command

   g++ -g -Wall -lboost_regex regex_match_example.cpp \
     -o regex_match_example

but I get many errors:

(Sorry for the messiness, I can't get Mozilla not to wrap those error 
lines.)

Anyone know what is going on here (a template instantiation problem 
perhaps)?

Thanks,

Cameron
