Trunk (as of yesterday evening), 2.6.4, export OPT='-O- -gl', make all, 
run with ./lazarus --sync --g-fatal-warnings.

The machines here are generally Debian with KDE as a desktop, but the 
"Wheezy" systems are closely modelled on the older "Squeeze" ones. It 
appears that if I run on the machine's own display it works, but if I 
attempt to run Lazarus over SSH (a combination that works on all other 
systems around here and with numerous programs on the test systems) it 
fails with

$ ./lazarus --sync --g-fatal-warnings
Xlib:  extension "RANDR" missing on display "localhost:10.0".
TMainIDE.ParseCmdLineOptions:
   PrimaryConfigPath="/home/markMLl/.lazarus"
   SecondaryConfigPath="/etc/lazarus"
The program 'lazarus' received an X Window System error.
This probably reflects a bug in the program.
The error was 'RenderBadPicture (invalid Picture parameter)'.
   (Details: serial 1054 error_code 188 request_code 155 minor_code 23)
   (Note to programmers: normally, X errors are reported asynchronously;
    that is, you will receive the error a while after causing it.
    To debug your program, run it with the --sync command line
    option to change this behavior. You can then get a meaningful
    backtrace from your debugger if you break on the gdk_x_error() 
function.)

Is OK over a remote X session (i.e. running in Xnest). An initial 
successful run to set up ~/.lazarus doesn't improve the situation over 
SSH but gets it to the point where lazbuild works.

However I also find that a program built using Lazarus (IDE or lazbuild) 
fails on that system (i.e. Wheezy) in the same way as the IDE.
