Yes..you may be having an issue with qt as I think vector is using 4 and the application is not compatible with 4 and must have qt3x..as noted on the link page. that is why I suggested you research the depends to insure it was possible as I did not know what version you were installing..am not familiar with the application.
A Linux or FreeBSD compatible or Mac OS X operating system.
Qt development library. At least Qt 3.3.* version. Qt 4 not yet supported
Berkeley DB database. At least db-4.1 version. FreeBSD users are required to use the 4.3 version.
TA-Lib Technical Analysis Library. At least ta-lib-0.3.0 version. See
EDIT: actually looks like vector has qt3.3.8b so should be ok and db aswell..
TA is o.4.0 but errors seem to start with qurlinfo
I would guess and try a lesser TA like 0.3.x or look into kde3 compatabilities
perhaps someone else with more familiarity will chime in
