<p><b>New page</b></p><div>If you want to use an existing installation of the 3rd party software <br />
(note that that in some cases VisIt requires older versions) you can <br />
force this with the following hack (uses Python as an example):<br />
<br />
From the directory you run build_visit from, run the<br />
command:<br />
<br />
mkdir -p visit/python/2.5/linux-x86_64_gcc-4.1.2 (last bit is architecture/compiler dependant)<br />
<br />
This will cause build_visit to think python is already installed,<br />
skipping the compile/install of it. However, after build_visit<br />
completes, you'll have to change your `host`.conf. Simply change the<br />
<br />
PYDIR=/some/long/directory/name<br />
<br />
line to:<br />
<br />
PYDIR=/usr<br />
<br />
This will cause VisIt to use your system's python.</div>Asis
