[Plplot-devel] Incorrect pkg-config link flags with plplot 5.11.0

[Orion P. <or...@co...>]

With plplot 5.10.0:

# pkg-config plplotd --libs
-lplplotd

With plplot 5.11.0:
-lplplot -lltdl -lm -lshp -lfreetype -lcsirocsa -lcsironn -lqhull 
-lqsastime

# pkg-config plplot --libs


This is wrong because the extra libraries are only necessary in the case 
of static linking.  To indicate this use Libs.private.  See also 
http://people.freedesktop.org/~dbn/pkg-config-guide.html

The attached patch fixes.  If some functions are referenced directly in 
the public plplot headers then you would need to add them to Libs.
