Building both the shared and static libraries seemed to do the trick. 
Now the challenge is libmp3lame, because that package does not generate 
a '.pc' file. I tried creating one by hand, using some of the others as 
models, but pkg-config doesn't recognize it. I built both the static and 
shared versions of the library, but no such luck. Anyone who has managed 
to build libmp3lame into ffmpeg and remembers what worked? I would sure 
appreciate it!

Thanks again,

Jeff
