Tvheadend

I tried compiling from latest source using the following commands:

./configure
make

If I then run it with './build.linux/tvheadend' everything works great. If I instead cd into build.linux and then run ./tvheadend, then the WebUI fails to start with:

Aug 11 14:21:25 [ERROR]:webui: No source path providing HTTP content: "/static". Checked in "/home/xbmc/Git/tvheadend/build.linux" and in the binary's embedded file system.
Aug 11 14:21:25 [ERROR]:webui: No source path providing HTTP content: "/docs". Checked in "/home/xbmc/Git/tvheadend/build.linux" and in the binary's embedded file system.
Aug 11 14:21:25 [ERROR]:webui: No source path providing HTTP content: "/docresources". Checked in "/home/xbmc/Git/tvheadend/build.linux" and in the binary's embedded file system.

The problem is, this also happens when I copy build.linux/tvheadend into /usr/bin.

Any ideas? From the playing around I've done in the source file, the EPG/Recording is 100x nicer, so well done.
