How far into the second UTM Zone does your region go? If not far and the
distortion is acceptable you can reproject 1 into the other.
Otherwise you need to find or create a Projection that does a better job
of covering your region. A UTM projection is unlikely to be a good
candidate in this case.
Tyler,
The general issue (also exists in QGIS) is that grid/graticule creators
commonly only create nodes where 2 lines intersect. The solution
generically is that you need to increase the node density of each line
so that there are more points to bend the line along when projected.

The suggestion is that your reinstall GRASS using the OSGeo4w64
installer. You likely used the OSGeo4w previously, which is a 32 bit
bundle of open source geo software. You can't just swap out the python
you have to get everything compiled for 64bit.
