[GRASS-dev] Building GRASS dev - editing ld.so.conf

[Paul Schrum]

Thank you Moritz.

Since I posted my original question, I have made some progress.  It is
putting the grass executable in
/usr/local/src/grass7_trunk/bin.x86_64-pc-linux-gnu

I was able to run this and run a module to verify that it looks right.
Thanks a lot for your help (and also to Vashek, who helped me in direct
emails.)

I will have more questions, but I will put those in other threads.

- Paul
