cannot find -lcsage error when creating clone

edit

After a fresh install of my Ubuntu 12.04 system I have trouble creating a clone (before the fresh install all worked without problems). The operation stops with the following error:

/usr/bin/ld: cannot find -lcsage

I can fix the error my manually copying libcsage.so into the ../devel/sage-test3/c_lib folder and the running

./sage -b test3

I have tried with different Sage binaries, the effect is always the same. This the complete output from the operation:

    Now cloning the current Sage library branch...
