In others distros, how is it?

No OK, KO.
if I do:
export PETSC_DIR="/usr/lib/petsc";
export PETSC_ARCH="linux";
./configure --disable-gzstreams;

I have
[....]
Compiling C++ (in optimized mode) src/mesh/mesh_data_unv_support.C...
Compiling C++ (in optimized mode) src/mesh/mesh_data_xdr_support.C...
Compiling C++ (in optimized mode) src/mesh/mesh_diva_support.C...
Compiling C++ (in optimized mode) src/mesh/mesh_exodus_support.C...
src/mesh/mesh_data_unv_support.C:29: gzstream.h: No such file or directory
Compiling C++ (in optimized mode) src/mesh/mesh_generation.C...
make: *** [src/mesh/mesh_data_unv_support.i686-pc-linux-gnu.o] Error 1

so, I think that the libmesh script doesn't like a debian system :-(

Regards,

Leo
