nco-3.1.9_1

[Takeshi Enomoto]

I revised nco-3.1.9 to enable ncap2 variants back.
<http://trac.macosforge.org/projects/macports/ticket/11611>

Please review this fix and commit.

BTW, the cause of the failure is case sensitivity
(there are Ncap2.hh and ncap2.hh in the same directory).
I moved ncap2.hh to ncap.hh and reinplace'd
#include <ncap2.hh> then extracted Ncap2.hh.
I wonder if there is a better way or standard solution.

Thanks.

Takeshi
