[igraph] ARPAC in 64 bits

I am new on igraph, so sorry if this is a silly question. I was trying to use the function igraph_eigenvector_centrality(...) so i tried to learn how to use this using the example in the igraph-0.5.4/examples/simple/eigenvector_centrality.c. Running it using an ubuntu 32 bits, I could get the correct results, however, running it using an 64 bits ubuntu i only got a segfault. 

(gdb) where
#0  0x00007ffff6ebf04d in dseupd_ () from /usr/lib/libarpack.so.2
#1  0x00007ffff7b43930 in igraph_arpack_rssolve () from /usr/lib/libigraph.so.0
#2  0x00007ffff7b4736a in igraph_eigenvector_centrality () from /usr/lib/libigraph.so.0
#3  0x0000000000400a4b in main () at eigenvector_centrality.c:40

The same result happened with the igraph_pagerank.c example file.

Could somebody help me showing how to use the ARPACK in an ubuntu 64 bits?

Thanks so much! =D
