boost/regex and gcc 3.0

hello all!

last night i downloaded the boost libraries. i ran into some problems 
and spent the rest of the night reading through this group hoping to 
find some answers... i found some similar problems, but they weren't 
the same, and i'm afraid that i didn't really understand the 
solutions (i'm a beginner/intermediate c++ programmer)...

my problem is this:

i am currently using gcc 3.0. As far as i know, it is the most 
current stable release (i.e. not beta). i installed the regex 
library. i created a simple test file that included the library and 
it worked okay (so it would appear that the compiler is having no 
trouble linking anything). however, as soon as i try to create 
objects from the library, i get errors.

below, i have the output of gcc -v, the commands i used to build the 
executable, and the first three errors output by the compiler. the 
code i compiled that gave me the erros was the "ftp based regex_match 
example" that came with the distribution. more detailed information 
(including source) can be seen at 
http://www.edmacdonald.net/error.txt  
this message is already long enough and i dind't want to pollute the 
list with a ton of text. if it would be more helpful for me to post 
the complete errors, let me know (they are lengthy). the web site is 
hosted from my house, so if the page doesn't come up, it's probably 
because my dsl is down (my provider is less than perfect)..

thanks!,
