Hi,

I recompiled all the fenics packages on my Ubuntu Jaunty amd64 and run
into trouble during linking:


mpic++ -o dolfin/libdolfin.so.0.9.2 -Wl,-rpath,/home/andre/local/lib 
-pthread -Wl,--export-dynamic -shared -Wl,-soname=libdolfin.so.0 
dolfin/ale/TransfiniteInterpolation.os dolfin/ale/HarmonicSmoothing.os

/usr/lib/gcc/x86_64-linux-gnu/4.3.3/../../../../lib/libumfpack.a(umfpack_dl_free_numeric.o): 
relocation R_X86_64_32 against `alocal symbol' can not be used when 
making a shared object; recompile with -fPIC
/usr/lib/gcc/x86_64-linux-gnu/4.3.3/../../../../lib/libumfpack.a: could

collect2: ld returned 1 exit status
scons: *** [dolfin/libdolfin.so.0.9.2] Error 1

has anybody else also ran into this problem? If I understood it 
correctly (which I do not assume :-)) I should recompile libumfpack.a 
with -fPIC options, but I read somewhere that due to the GOT (global 
offset table) in the library it is considered as a bad idea to proceed 
in such a way with a *static* library... hmm :-/
Any ideas?
