How do I install a package 'TOPCOM'

Recently I have used the Sage Notebook for computing the triangulation of polytopes. To check the regularity of these triangulations, I need to install the package 'TOPCOM' in advance. But I can't install this software successfully. For example, if I command

sage: install_package('TOPCOM')

then there is a technical error and a caution; Error: failed to download

My laptop is a Mac OS X Version 10.6.8. Could you tell me how to fix this problem?

Volker, thank you for your answer. Alas, following your instructions produces exactly the same error message on my MacBookPro with OSX 10.8.2 as using the Sage session:

Do you have Xcode installed?

Though interestingly, it still says gcc is there, just that it doesn't work.

I'm guessing that it's the gcc installed in SAGE_ROOT/local/bin (note that this seems to be a binary installation of Sage), but I don't think that one will work unless Xcode has installed the various system libraries etc. I'm not sure, though.

Can you try the new spkg at Trac #13499? The easiest way is to open a terminal, go to the Sage directory, and run

[user@localhost Sage]$ ./sage -f

Also ticket needs review if you want the updated version distributed with Sage...
