Hi Marius,

with the introduction of the Arpack dependency for Octave 3.1.5x and following I 
had the same problems as you. Here is a little description about what my 
problems have been on OSX in detail and maybe this also then helps for you. 
Definitely I can say that Arpack is a beast, but once compiled correctly it 
works perfectly ;-)

I used fort77/f2c before and I downloaded the original Arpack *.tar.gz from 
their website. This combination does not work for me at all until today. Next I 
have chosen to switch to g95 instead of fort77/f2c and things became much better 
but still not absolutely good (some of the eigs.cc errors disappeared but some 
still where present and the svds.m error, too). Finally I switched to Debian's 
Arpack source package found here

http://ftp.de.debian.org/debian/pool/main/a/arpack/arpack_2.1+parpack96.dfsg.orig.tar.gz

and voila, everything worked perfectly (together with g95). I also have to say 
that I compile Arpack against vecLib's Lapack, like this

    ARPACKLIB  = $(home)/libarpack.a
   -LAPACKLIB =
   -BLASLIB =
   +LAPACKLIB = -Wl,-framework -Wl,vecLib
   +BLASLIB = -Wl,-framework -Wl,vecLib

So what I want to say in short ;-) try to choose Debian's Arpack source package 
and make sure once again that your Fortran compiler is well suited to compile 
Arpack correctly. Finding out this took me, I remember, 5..6 evenings or even 
more, so I really hope you can save some time ;o)

I see the three src/data.cc errors, too. This is a problem of our g++ compiler 
that produces another result than on Linux and other systems, no idea how to fix 
this, see

http://www-old.cae.wisc.edu/pipermail/bug-octave/2008-August/006584.html

I cannot see your last error in fft.cc. But I've got another one in 
test_diag_perm.m.

Good luck,

   Thomas
