Ben, Thanks for the hints!
I will try gfortran, but first I see maybe another problem:
you are adding the flag '-ff2c' when building qrupdate,
do you also have that in the Octave configuration?

I have the following for qrupdate:
FC=g95
FFLAGS=-g -O3 -funroll-loops
FPICFLAGS=-fPIC
BLAS=-Wl,-framework,Accelerate
LAPACK=-Wl,-framework,Accelerate

and for Octave I use:
./configure F77=g95  CPPFLAGS="-I/sw/lib/flex/include -I/sw/include"  
LDFLAGS="-L/sw/lib/flex/lib -L/sw/lib -L${PWD}/../arpack -L${PWD}/../ 
qrupdate-1.1.0" --prefix=/opt/octave/3.3

which means FFLAGS is left at its default:
-O -mieee-fp

Maybe I should rebuild all with -ff2c?
c.

P.S. even if I get passed the problem with qrupdate, it seems I should  
expect more trouble later,
building with --without-qrupdate I get
