Why do I have multiple versions of gcc?

[jonantice]

Is it normal to have this many gcc's at once?

gcc 4:4.0.2-2 4:4.0.2-2 4:4.0.2-2 install

The last line of gcc -v: gcc version 4.0.3 (Debian 4.0.3-1)

yeah, when compiling a package it must be compiled with the same version it was originally. so brand new packages are likely to use the newest gcc, packages that were developed under gcc 3.x cant compile on gcc 4.x

I think you don't need more than two--the one that was used to build your kernel for when you need to compile kernel modules, and the latest one for everything else.
