I've installed GRASS 7 on Ubuntu by compiling from source

I'm running this on a server, so don't have a GUI. Does this
mean that GRASS hasn't installed correctly?
no, it is probably just fine. you get that because there is no
~/.grass7/rc file existing yet so the last mapset and location
used is <UNKNOWN>. Yes we need to clean up the new startup
script, but bear with us, 7.svn is still the in-development
version.. 
the fix is easy, just point it to an existing mapset:
$ grass70 ~/grassdata/spearfish60/user1
then it will be happy. If it continues to complain about no
GUI available (it shouldn't) use the g.gui module to set the
default to "text".
I expect that we'll change/improve the GRASS_BATCH_SCRIPT logic
in 7, but that's still mostly on the TODO list.
