Hello all. Here is another KDE 4 dependency, used in some packages, and KDE folks has plans to use it even more. Tested on i386 and amd64. The port is loosely based on FreeBSD one.
Qalculate! is small and simple to use but with much power and versatility underneath. Features include customizable functions, units, arbitrary precision, plotting, and a graphical interface that uses a one-line fault-tolerant expression entry (although it supports optional traditional buttons). This package contains the shared library used by all Qalculate! frontends. (yes, I didn't port any GUI frontends as they were not needed) -- WBR, Vadim Zhukov
