On i86, I installed SDL-1.2.2.tgz as a binary package, as well as smpeg-0.4.1.tgz.

I tried to pkg_add SDL-mixer-1.2.0, but it requires smpeg version 0.4.3.

I got the source for smpeg 0.4.3, and attempted to build in pkgsrc; the make script fails because it cannot compile the SDL test
program.  It mentions the sdl-config program, but I believe it is configured correctly.

The output mentions undefined references to XF86VidModeSetGamma, and others.  Do I need to update to newer X86 libraries somehow?
Has anyone built SDL/smpeg/SDL-mixer on NetBSD 1.5?

The output of the attempt to build the SDL program is:
configure:2104: checking for sdl-config
configure:2139: checking for SDL - version >= 1.2.0
configure:2224: cc -o
