I didn't notice -lXmu in the linker command line.  I'm not an expert in those 
Makefiles - they work in different way on each system. You can force linking 
to Xmu by modifing following lines in Makefiles, this should solve the 
problem. 

kmatplot/demos/Makefile.am:
demo2d_LDADD = ../widgets/libplot.la $(LIB_QT) -lXmu $(GLLIB)
demo3d_LDADD = ../widgets/libplot.la ../opengl/libqgl.la $(LIB_QT) -lXmu 
$(GLLIB)

kmatplot/Makefile.am:
kmatplot_LDADD = ./part/libkmatplot.la -lXmu

I don't know why  you are obtaining  plenty   of warnings ( some pedantic gcc 
version ? ) but probably you can safely ignore them all.
