Thanks I'm recompiling Cairo.  One thing.   I can only get it to compile with static libraries!  Is that a problem?
 
I get the following error:
 
/usr/lib/liblzo2.a(lzo2a_9x.o): relocation R_X86_64_PC32 against symbol `memset@@GLIBC_2.2.5' can not be used when making a shared object; recompile with -fPIC
 
 
thanks
