If you rebuilt NEdit from CVS, it does that by itself. Quote from
nedit.c (sorry about the linewrap):

    /* X.Org 6.8 and above add support for ARGB visuals (with
alpha-channel),
       typically with a 32-bit color depth. By default, NEdit uses the
visual
       with the largest color depth. However, both OpenMotif and Lesstif
       cannot handle ARGB visuals (crashes, weird display effects, ...), so
       NEdit should avoid selecting such a visual.
       Unfortunatly, there appears to be no reliable way to identify
       ARGB visuals that doesn't require some of the recent X.Org
       extensions. Luckily, the X.Org developers have provided a mechanism
       that can hide these problematic visuals from the application.
This can
       be achieved by setting the XLIB_SKIP_ARGB_VISUALS environment
variable.
       Users can set this variable before starting NEdit, but it is much
       more convenient that NEdit takes care of this. This must be done
before
       the display is opened (empirically verified). */
    putenv("XLIB_SKIP_ARGB_VISUALS=1");
