[Libreoffice] Error in/at end of make install

after the make, make install runs fine for some time but finishes with 
these last lines:
"
Entering /home/cono/src/git/libo_core/instsetoo_native/util

dmake:  makefile.mk:  line 239:  Warning: -- Prior to dmake 4.5 only one

No EPM: do no packaging at this stage

mkdir /usr/local/lib/libreoffice: Acces refures at 
/home/cono/src/git/libo_core/solenv/bin/ooinstall line 49
make: *** [install] Error 9

"

And indeed, I cannot start the programm in the following way, that I was 
able before:
"
  cd /home/cono/src/git/libo_core/install/program
  . ./ooenv
  ./soffice.bin
"

something wrong in make install or new methodology?

Thanks for advise...
