[Qt] Linking error with Lazarus Qt on Mac OS X 10.5

I tried again this morning with the snapshot from 26 dec 2008 (the 
snapshot from 27 dec 2007 crashes upon opening my project). I recompiled 
the LCL via the menu Tools/Configure "Build Lazarus", selecting the 
'Clean all' and 'With packages' options. I passed "-dUSE_QT_44 
-k'-framework' -k'Qt4Inft' -k'-lobjc' -k'-framework' -k'Foundation'" in 
the Options edit box.
Now simple projects no longer have a linking error... but since package 
installation is still VERY broken with the snapshots, the whole thing is 
useless for my projects requiring DB access and reporting.

How can I get Qt to work with the stable version of Lazarus (0.9.26) ?
