Currently, this snippet of perl core core dumps:
use SDL;
	I discovered this while trying to build a package that needs the p5-SDL
package.  (games/frozen-bubble) After ktracing it and noticing that it crashes
soon after mmaping libpthread I tried relinking the perl binary with -lpthread.
That worked.  Is that the right solution?  Or, is "link libpthread at link time
into everything that might dlopen it at runtime" just the best answer we have
right now?
