Apps Problems building from eclair branch

[death2all110]

Hello, i think this is the right forum but move if needed. Anyway im working on building from source from the eclair branch for the LG Ally. Following directions outlined in the readme with the VS740 Source. however i get as far as running make -j4 and at that command is where im running into problems

Ubuntu 10.10

This is the output i get:

blake@blake-Satellite-A505:~/mydroid$ sudo make -j4
