libgsl.so.0 => /usr/lib/libgsl.so.0 (0x00007ff78f072000)
is not valid. My setting LD_LIBRARY_PATH is wrong.
After correcting this, 
pkg install of gsl package went well with gsl-2.1 (on 4.0.3 and 4.1.0+).

Sorry for my inadequate writing.
And found that this is not LD_LIBRARY_PATH issue
but LD_PRELOAD.


/home/tatsuro/work/gsl/gsl-2.1_inst is gsl-2.1 install directory.

Setting LD_PRELOAD to (directory used shared libgsl exist)/libgsl.so 
before octave execution seems to be required.

Is there such mechanism to pass such values from octave in the pkg command ?
