FWIW, recently csup stopped working for me in -current on i386. It fails 
when checking the errno set after calling access() to check if a file 
exists:

Updater failed: Cannot create directories leading to "/usr/ports/science/p5-Algorithm-SVMLight/Makefile": Unknown error: 0

According to gdb, errno is being set correctly but changes almost 
immediately back to zero. Not sure how/why, and I'm not sure that I'm even 
using gdb correctly for threaded applications. Switching to libthr with 
libmap.conf results in the same error.

I swear that it had something to do with turning on symbol versioning, but 
attempting to turn it back off was not a fun experience and didn't have 
the patience to see it through.
