you'd set the fillstyle "solid" globally. The reason why
the polygon of \ncline is also filled

\begin{PstGanttChart}[yunit=1.5,xunit=3.5,ChartUnitIntervalName=,
                       ChartUnitBasicIntervalName=Week,
                       TaskUnitType=Week,
                       TaskOutsideLabelMaxSize=0,ChartShowIntervals]{3}{10}
   \PstGanttTask[TaskOutsideLabel={III.h Interface CaMuS}]{0}{5}{3h}
   \PstGanttTask[TaskInsideLabel={IV. Pre-live 
fase},TaskStyle=TaskStyleB]{2}{7}{4}
   \PstGanttTask[TaskOutsideLabel={IV.b Data-entry content}]{4}{6}{4b}
\end{PstGanttChart}
%
\psset{fillstyle=none}
\ncangle[angleA=0,angleB=90]{->}{3hEnd}{4bTop}
