I have libqt4intf.so.5.1.72 which I believe is the latest.

However I also have libqt4 4.4.3 which is < 4.5 mentioned on the 
libqt4intf page.

So it looks like I would need to upgrade my qt4 libs into the world of 
debian testing/unstable, in order to compile laz with qt. This is not 
exactly comfortable, as I'm concerned that doing so could break my kde 
desktop and many apps.

I wish I could have garnered that requirement by reading those pages. 
Though it does list the higher versions of qt4, it nowhere says that I 
would be required to install those versions of all qt4 libs.

I am not sure how it ought to read, but my guess would be something like 
this:

Version info

The latest libqt4intf requires Qt >= 4.5.2

V1.72: 21 Sep 2009: Improved signal hooking/method overriding, 
Windows:renamed types likes HDC to avoid name clashes
V1.71: 15 Sep 2009: requires Qt >= 4.5.2, WebKit improvements 
(qlclwebpage/qlclwebview/qlclnetworkcookie),qlclthread, versioning, 
lclwebkit demo

sigh.
Thanks for all your help! Maybe some time in the future I will be able 
to upgrade to qt lazarus.
