Ole and Sebastian, FWIW, I have just seen the same thing using cerbero 
1.2 branch on Precise.

I worked around this temporarily by finding where '-prefer-non-pic' was 
being added to liba52's compiler flags and disabling that.

Specifically, I found line 12687 (!) of the configure script in 
a52dec-0.7.4:

LIBA52_CFLAGS="$LIBA52_CFLAGS -prefer-non-pic"

I commented that out (prepended a #) and the a52 build worked.

Cheers,

Mark.
