Anthony,

You have a copy of readline in /usr/local.
This copy is a recent version unlike the one in /usr/lib and it  
defines symbols with an rl_ prefix:

But here, ld tries to link with the copy in /usr/lib which doesn't  
have such symbols:

The only good solution to this would be to add /usr/local/lib in the  
library search path when building base/ but it's contrary to the  
tradition of darwinports which says that /usr/local is evil.  
Preventing gcc to use /usr/local/include would cause way too much  
harms by preventing the software to be compiled on non-standard  
installs.
