make reinstall does not work

[Walter Schwarzenfeld]

I had a strange error: Make reinstall does not work anymore in the port 
(10.3-amd64) also FORCE_PKG_REGISTER.

All other make commands works fine. I don't know if it is related to 
FLAVORS.

make reinstall ended up e.g. with:

  Registering installation for gtk2-2.24.31
*** Error code 70

Stop.
make[2]: stopped in /usr/ports/x11-toolkits/gtk20
*** Error code 1

Stop.
make[1]: stopped in /usr/ports/x11-toolkits/gtk20
*** Error code 1

Any idea or suggestion?
