This reminds me of a frustrating experience I had last week when IDL
would hang after I added a large directory structure to the !PATH. It
turns out that there was a bad logical directory link that was putting
IDL into an infinite loop trying to resolve the subdirectories. I only
solved the problem after switching back to V5.5 which gave explicit
error messages -- unlike V6.0 which would hang silently.

As for your original question, I can only think of the crude method of
explicitly removing directory names from a string created using
EXPAND_PATH before adding it to your !PATH, e.g. to remove the directory
/home/landsman/pro/bte from the list of directories in
+/home/landsman/pro in your startup file

st = expand_path('+/home/landsman/pro')
st = repstr(st,'/home/landsman/pro/bte:)
!path = st + ':' + !path

where repstr.pro (ftp://idlastro.gsfc.nasa.gov/pub/pro/misc/repstr.pro)
removes the target string from object string.
