[Scons-users] Adding my tools to the site specific directory

[William Blevins]

Pedro,

The last time I used "site_scons/site_tools" for custom scanner/emitters in
SCons 2.3.0 on RHEL5 under the python 2.4, and it worked as expected.

Going out on a limb here, has someone add "--no-site-dir" to your
SCONSFLAGS?

Other than that, I cannot think of anything ;(

V/R,
William
