I hope this email is properly inserted in the thread. Just need to say 

With your reassurance, I went ahead and compiled and installed the ncurses 
5.4 source. (I've been burned more than a few times replacing the bundled 
rpm binaries.) I configured with the overwrite prefix, and with shared 
library and gpm mouse.

The new install returned TRUE to "can_change_color()" using the same test 
program !!! Other little test programs now seem functional, too. Thank you. 
My guess is the new source recompiles a new teminfo library??

One little "whine" is the color change test. The color sample pane doesn't 
change, but black and white (bg and fg) change following the cursor.

Thanks again; excellent software. (I am now curious about your xterm work.)
