I have a Python 1.5 package (PR#4764, files at
I'm still waiting for it to be comitted to pkgsrc.

I didn't need any patches at all for 1.3. The only patch in my package
is the "re.1" patch from

However, looking into it now, I see at least a couple things that could
use changing. First is the comment "NetBSD shared libraries (not quite
SVR4 compatible)". I'm not sure exactly what this is in reference to,
(dlerror?) but it seems odd. Next is that NetBSD does have dlerror() in
1.3, so the #define of that should be removed for 1.3 and later.

You can test for this by comparing against the symbol NetBSD from
<sys/param.h>.  1.3 is 199712. (This assumes dlerror() was introduced
between 1.2 and 1.3, which I think is correct).

The following is a quick and dirty patch that works on 1.3 (modulo a
warning: MAXPATHLEN is redefined between python's osdef.h and
sys/param.h) and that _should_ work on earlier versions since it
preserves the old behavior in the pre-1.3 case.
