Ok, Logged into scratchbox, tried the 'apt-get full-upgrade' -> Invalid operation, so I did a regular 'apt-get upgrade' but nothing got updated

Even though I'm connected to the internet, I still get the same error message in the console window:

configure: error: Package requirements (hildonmm libosso) were not met:
No package 'hildonmm' found
Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix.
Alternatively, you may set the environment variables HELLOWORLD_CFLAGS and HELLOWORLD_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
*** exited with code 1

I tried it being logged in at scratchbox and not being logged in, but this doesn't change anything...
