I tried FreeBSD, but X always seg failed, so then I tried PC-BSD.

The qt4 ports install include files to close to qt3 include files (you fall on qt3 files first). The PREFIX stuff does not work. 
The qt4-gui ports does not link with the PREFIX (does not find libqtcore, whatever you do with ldconfig)

If you play with ldconfig, bash becomes unstable-> you cannot launch
any program or any new konsole anymore, the messages you get are common problems
(google says: update ports recompile everything, but my ports are fresh :-) -> 
reboot -> I have never rebooted this much :-(.    (BSD ? :-)

with LD_LIBRARY_PATH and a manually (no ports) compiled qt4 (put in /usr/local/KDE4) I can finally compile lazarus 
(some pthreads link hurdle aside)

lazarus compiled with:
#!/bin/bash
cd lazarus
export LD_LIBRARY_PATH=/usr/local/KDE4/lib
gmake LCL_PLATFORM=qt clean all OPT="-dDEBUG -dUSE_QT_4_3 -k'-L/usr/local/KDE4/lib' -k'-lpthread'"

qt4intf compiled with:
cat ./compile_lib.bash
#!/bin/bash
export QT4=/usr/local/KDE4
export QT4I=$QT4/include
export LD_LIBRARY_PATH=$QT4/lib
if [ -e "$LD_LIBRARY_PATH/libQtCore.so.4" ]
then
  g++ -D UNIX -I. -I$QT4I -I$QT4I/Qt -I$QT4I/QtGui -I$QT4I/QtCore -Iqlcl 
qtpas.cpp -o libqt4intf.so -shared -fPIC -Xlinker $QT4/lib/libQtCore.so.4 
$QT4/lib/libQtGui.so.4 "-soname=libqt4intf.so"
  strip --strip-all libqt4intf.so
else
  echo "Please Modify location of Qt4 in this script"
fi


lazarus runs, but has continuously exceptions:

I also noticed that the gtk2 version crashes when started with ./startlazarus but runs fine when started with ./lazarus ???

so something is wrong ...
