Then you are somehow still linking with the old library. You can check
by typing "ldd gmsh".

If you have installed the dynamic gsl libraries in a non-standard
location, you will probably have to add
'-Wl,--rpath,/path/to/dynamic/library' to 'LINKER' in gmsh's 'variable'
file and relink the code. Alternatively, you could edit the
'LD_LIBARY_PATH' environment variable or use the 'ldconfig' program to
reconfigure ld.

(Although the simplest solution is probably to either link with static
gsl libraries, or use the binary version available on
http://geuz.org/gmsh/bin/...)

Cheers,

Christophe
