[GRASS-GUI] r.patch from GUI not creating all files

I am encountering a problem running r.patch from the Tcl/Tk Gui in GRASS
6.4.0 (RC4). I am running the Kyngesburye build, on Mac OSX 10.5.6.,
and have all of the current frameworks, along with ActiveTcl version
8.5.6. The problem is as follows:
I am trying to patch together multiple raster maps using r.patch. After
setting the region to include all of the raster files I am patching
together, I attempt to run r.patch using the GUI. I choose the
necessary raster maps that I wish to patch together from my raster map
list, then enter a name for the resultant raster map. When I hit run,
the command processes (the green bar fills up), but when it completes
the patch, in the output window, I get an error saying GRASS is unable
to find the resultant raster map in my mapset. For example, if I were
trying to patch raster maps together to create a resultant raster map
called "patched_map" in a mapset called "county", this would be the
error that displays in the output window after running r.patch:
Unable to find 'patched_map' in 'county'
Creating support files for raster map <patched_map>
If I list all of my raster files, the resultant raster map from r.patch
(patched_map) does not appear.
Being unsuccessful running r.patch from the GUI, I decided to run it
from the command line. Here is the command that I entered:
r.patch input=map1 at county,map2 at county output=patched_map2
This is the same exact command (except for the slightly altered output
name) that appeared at the bottom of the r.patch GUI window. However,
after running r.patch from the command line, the resultant raster map
(patched_map2) does appear in my raster map list. I therefore decided
to search my filesystem to try and find instances of the resultant
raster map that I tried to create using r.patch from the GUI
(patched_map), and compare them to the files I have for the resultant
map that I created from the command line (patched_map2). Here is what I
It appears that some files for the r.patch resultant raster map were not
created when running r.patch from the GUI. There is no instance of
"patched_map" in the 'cell' folder, the 'cellhd' folder, or the 'fcell'
folder. Any ideas as to why these files are not created when running
r.patch from the GUI, while they are created when r.patch is run from
the command line? I am unsure if this is a GUI bug, or if there is a
part of my overall GRASS build that needs to be added/updated.
Many thanks for your help, and if you need additional information or
clarification, please ask.
