Adriaan, Thanks for continuing to push KDE for Solaris. Unforunately, I've gotten symbol not found errors since the last set of packages. I got rid of everything and started clean with yesterday's spec files and got the same problem.
Here's the error from kcalc : /opt/kde-4.1/bin/kcalc ld.so.1: kcalc: fatal: relocation error: file /opt/kde-4.1/lib/libkdeinit4_kcalc.so: symbol __1cIQdDMapDataLshared_null_: referenced symbol not found
