You can use Boost.Regex in a dll by defining BOOST_REGEX_DYN_LINK when 
building your dll, but as long as the regex code is isolated to your dll and 
doesn't spill over into it's public interface then this shouldn't be 
necessary.  Other than that it's hard to say what the issue might be without 
seeing your code.
