Sure, no problem...I built these extensions using 
tc-ext-tools: 
http://code.google.com/p/tc-ext-tools/First, you must install tc-ext-tools (you need svn.tcz):
tc@box:~$ tce-load -i svn
tc@box:~$ svn checkout http://tc-ext-tools.googlecode.com/svn/trunk tc-ext-tools
tc@box:~$ cp config.sample .config
tc@box:~$ ./install.sh
tc-ext-tools has been installed. Now you build 
fpc package:
tc@box:~$ svn checkout http://tc-ext-tools.googlecode.com/svn/packages/fpc
tc@box:~$ cd fpc
You must edit 
common file. Change:
VERSION="2.6.2" to 
VERSION="2.6.4"and 
CURRENT="Updated to $VERSION (by AmatCoder)" to 
CURRENT="Updated to $VERSION (by Zendrael)"Then:
tc@box:~$ buildit
When it is finished (takes more than 15 minutes) you have a 
fpc-2.6.4.tar.bz2.bfe file under 
/storage/pkgs folder. Save it because you will send this file to tcesubmit.
Reboot and load 
fpc.tcz. As you can seen it has been updated in your 
/tce/optional directory. Now repeat with 
lazarus.
