#4916 arpack-ng-3.4.0-1 (dependency on gcc6)

[Remko Scharroo]

In order to start making arpack-ng depend on gcc6, I simply replaced "gcc (5)" by "gcc (6)".
But since a new version of arpack is now available, I also change the version number from 3.3.0 to 3.4.0.
Then, the lapack dependency (for arpack-ng-ref) used to be to lapack 3.5.0 (which itself still depends on gcc5).
Instead of updating lapack 3.5.0 to use gcc6, I rather made arpack-ng-ref depend on lapack 3.6.1, which already depended on gcc6.

Successfully compiled and tested with fink -m build.
