Based on that page, it looks like trickle was created in 2003, updated for three months, then never updated again. This says to me the software is dead and obsolete.

The page also says "trickle works by taking advantage of the unix loader preloading". I don't know what "the unix loader preloading" is but I wouldn't be surprised if Mac OS X uses a different mechanism which trickle would not be compatible with.

This error can be overcome by changing line 484 of trickle-overload.c so that nfds is defined to be not of type int but of type nfds_t, matching line 114 of poll.h. However the next error I then encounter is:

creating libtmptrickle-overload.so.la
(cd .libs && rm -f libtmptrickle-overload.so.la && ln -s ../libtmptrickle-overload.so.la libtmptrickle-overload.so.la)
cp: .libs/libtmptrickle-overload.so.so: No such file or directory

".so" is a library extension used on other UNIX-like operating systems but not Mac OS X. The fact that the software doesn't know this indicates that this software was never designed to compile on Mac OS X, or at least was never tested on Mac OS X.

We cannot create ports for software that does not work or compile on Mac OS X. If you want to see trickle on Mac OS X, work with the developer of the software to make that happen. Once they release a new version of the software that works on Mac OS X, we can certainly look into creating a portfile for it to ease installation.


I'll attach the portfile and patch I used to get this far.
