Installation error

Hi, I installed OpenMX following instructions here http://openmx.psyc.virginia.edu/2015/01/version-201-now-available

Installation went through but I noticed an error

mkdir -p ../inst/debug
cp *.gcno ../inst/debug/
cp: cannot stat ‘*.gcno’: No such file or directory
Makevars:40: recipe for target 'save-gcno' failed
make: [save-gcno] Error 1 (ignored)

Not sure if that is important. I am using R 3.2 on Ubuntu 15.04 64 bit.

Thanks
