 I've now built it, and tried it for a couple of minutes - far too
complex for me!  It's for mathematicians (I don't even know what
many of the things in the menus are).  For my use (mostly, keeping
track of my finances) using the history to store a partial
calculation is possible, but feels awkward.

 Build order / required deps:

libxml2
glib2
gtk+-2
libglade
rarian (i.e. scrollkeeper)
cln-1.3.2
libqalculate-0.9.7
qalculate-gtk-0.9.7

 There are other deps if you wish to retrieve exchange rates (!) or
for graphical plotting.

 cln does install a "useful" program: /usr/bin/pi will output pi to
an arbitrary number of digits (default is 100) -
ken@jtm1 ~ $/usr/bin/pi 70
3.141592653589793238462643383279502884197169399375105820974944592307816
but it truncates after the last digit printed -
ken@jtm1 ~ $/usr/bin/pi 5
3.1415
which was not what I expected : at school I was taught that 3.1416
was adequate for anything we were likely to do.

 There are lots of warnings from cln about using obsolete/deprecated
headers, but fedora build it so I guess they will have fixes when
g++ or whatever changes.
