Your perl was compiled with gcc-4.7 and so that is what gets used when 
you build a module with C code. My raspberry pi is at work right now so 
I cannot check but basically the build is attempting to run gcc-4.7 and 
it either does not exist or is not on your path.

What do you get when you type the following at the command line:

$ which gcc
$ gcc
$ gcc --version
$ gcc-4.7

If gcc --version reports 4.7 then you can probably get away with adding 
a symbolic link in whatever dir gcc is found (see which gcc above) from 
gcc-4.7 to gcc. Something like:

cd /usr/bin
ln -s /usr/bin/gcc gcc-4.7

but that depends on what which gcc and gcc --version says.

BTW, I'm on irc.perl.org in the #dbi channel (as mje) if you want a chat.
