Ramesh - There is probably another, older version of the GSL on your
system that the dynamic library loader is picking up (to make sure, type
'ldd gmsh').

To fix it, you can

- change the order in which ld is looking for dynamic libraries (e.g.,
by using the LD_LIBRARY_PATH environment variable; see 'man ld' for more
info);

- or, if you are using gcc, force the path in the linking options (e.g.
editing the 'variables' file and adding '-Wl,--rpath,/path/to/gsl/lib'
to the LINKER variable);

- or, force linking with the static version of the new gsl (e.g., by
replacing '-lgsl' with '/path/to/gsl/lib/libgsl.a' in the 'variables' file).

Cheers,

Christophe
