Indeed, the configure script automatically sets CFLAGS, CXXFLAGS, and FFLAGS to 
include the options
-fPIC. The option is necessary on my system (x86_64-unknown-linux-gnu, Suse 
10.0) and some configure
scripts don't test if this option is necessary. But the configure script of 
octave detects correctly
this option. And I wasn't aware that the optimization is disabled by setting 
explicitly *FLAGS!

John, thanks for pointing this out!

Jan, finally the configure line is:
 ./configure F77=gfortran CPPFLAGS="-I$HOME/Download/UFconfig 
-I$HOME/Download/AMD/Include
-I$HOME/Download/UMFPACK/Include -I$HOME/Download/CHOLMOD/Include 
-I$HOME/Download/COLAMD
-I$HOME/Download/CCOLAMD -I$HOME/Download/CXSparse/Source "  
LDFLAGS="-L$HOME/Download/AMD/Lib
-L$HOME/Download/UMFPACK/Lib -L$HOME/Download/CHOLMOD/Lib 
-L$HOME/Download/COLAMD
-L$HOME/Download/CCOLAMD -L$HOME/Download/CXSparse/Source -lg2c -lpthread" 
--enable-shared
--enable-dl --disable-static --prefix=$HOME/local64/octave-2.9.9
--with-blas=$HOME/Download/GotoBLAS/libgoto.a

If you still have problems to install octave, can you send us the file 
config.log and the error
messages you are seeing?

Cheers,

Alex
