libSDL-1.1.so.7 - Undefined symbol "pthread_mutexattr_init"

[Parv]

I tried to build "a 3D Engine in Perl" ...

  http://www.perl.com/pub/a/2004/12/01/3d_engine.html


... which led to failure that, long story short, libSDL-1.1.so.7 was
not somehow linked w/ pthread library; use of "SDL::App->new()"
resulted in ...

  /usr/libexec/ld-elf.so.1: /misc/local/lib/libSDL-1.1.so.7: Undefined symbol "pthread_mutexattr_init"


Running nm(1) on /misc/local/lib/libSDL-1.1.so.7 shows that all of
pthread_* symbols are undefined; ldd(1) shows ...

Any suggestions?
