A while ago I had suggested updating pcre to something not so  
prehistoric, but at the time concerns were raised about library  
compatibility. Recently. I looked closely at the current version,  
7.0, and compared it to Fink's 4.5. I can't find any reason why we  
couldn't update the package to the latest version.

Yes, there are 4 new functions added to the library, but adding  
functions doesn't break backward compatibility. If that were the case  
then anything built on Panther shouldn't work on Tiger. :) There are  
a couple of new fields added to the end of two structs, but again the  
developers designed this with backward compatibility in mind by  
requiring flags to be passed in to enable those fields.

While upstream hasn't rigorously followed libtool versioning  
guidelines, even if they had, the install_name would still not have  
changed since 4.5 since CURRENT and AGE would still be the same.

I've done some testing and encountered no issues, but I'd appreciate  
it if others could test as well. I can confirm, for example, that  
bluefish built against pcre 4.5 works fine with pcre 7.0. Postfix and  
nmap also seem to work.

I've put the info file in my experimental directory at danielj/10.4/ 
pcre.info for anyone who would like to try it.

Thanks.
