[Laszlo-dev] Build instructions

[Rami Ojares]

Ok here are the changes I had to do to get the build happening on linux 
ubuntu.

- create a new user who had an empty $HOME library so I could put the 
src and lib dirs right under home and not change the home for the session.
- Make the following changes to setup-lps.sh
1) uncomment
#export ANT_HOME=${ANT_HOME:-"${LZ_INSTALLS_ROOT}/apache-ant-1.6.5"}
and change the ant version to 1.7.1
2) add the line
export LPSHOME=${LPS_HOME:-"${LZ_LPS_ROOT}"}
in order to get LPS_HOME variable.

Now the build is getting farther BUT it stops at task lzl:

lzl:
      [echo] Compiling 
/home/laszlo/src/svn/openlaszlo/trunk/lps/includes/lfc/lzpreloader.lzl
      [java] org.openlaszlo.sc.CompilerError: createCompilationWorkDir: 
cannot get temp directory: null: java.io.IOException: Permission denied
      [java]     at 
org.openlaszlo.sc.SWF9External.createCompilationWorkDir(SWF9External.java:315)
      [java]     at org.openlaszlo.sc.lzsc.compile(lzsc.java:362)
      [java]     at org.openlaszlo.sc.Main.main(Main.java:23)
      [java] Compilation aborted.

So the process is trying to create CompilationWorkDir but where I don't 
know?!?
I made sure that my user has all privileges to the temp folder which in 
linux is /tmp
So that is not the problem here.
