I want to compile something downloaded with Fink from source. I tried and got an error that I didn't have any suitable compiler. I installed gcc-4 from Fink without trouble, and then tried again. It still couldn't find gcc, so I realiased gcc-4 to gcc. Now it recognised the compiler but said it couldn't output executable files, so I changed the alias back and then tried to install gcc from Apple's developer kit. It says it installed, but a Spotlight search for gcc and `which gcc' from a command prompt both return nothing (except the files for gcc-4, in the former case). Any suggestions?
