depothelper gcc-4.2.3 install failed

Hello all,

I tried installing gcc-4.2.3 using the tool depothelper. After installing some prerequisites it downloaded gcc-4.2.3 but then failed. Its output was Package-version gcc-4.2.3, Comment Requested, Download Using cache, Install FAILED. What can I do to find out why the download failed?

Thanks in advance,

Jörg
