Bugzilla Bug 12913

When attempting to merge KDevelop 3.0 alpha2, the following error occurs when
compiling lib/util/processwidget.cpp:

processwidget.cpp: In constructor `ProcessWidget::ProcessWidget(QWidget*, const
   char*)':
processwidget.cpp:55: no matching function for call to `KProcess::setUseShell(
   bool)'

please post the output of 'emerge info'. 

No problem:

which qt/kde are you using? 

Got exactly the same problem here.   ACCEPT_KEYWORDS="~x86"  QT: 3.1.0-r1 KDE:
3.0.5a  

QT:  3.1.0-r1
KDE:  3.0.5a

kdevelop-3.0_alpha2 currently only compiles with kde-3.1 or <kde-3.0.5, working
on 
a patch, stay tuned 

fixed in cvs, thanks.
