[Hampshire] compile

Help! I have been trying (for real, this time) to install Sunbird. I have
downloaded, unzipped and extracted the tarball and now have all the necessary
files in a directory called "sunbird".

So I changed directory to sunbird and tried to run ./configure. I also tried
to install configure, but could find only configure-debian, which I duly
installed with aptitude. I then started trying to run ./configure again.

The result is below.(1) What am I doing wrong?

TIA
Lisi
