It's a slightly generic message. The build process generates some mini test programs and tries to compile them, in order to verify things about your environment (eg is there a C compiler, does it support certain features etc.)

The fact that it passed some of the checks probably means it's not as simple as there being so developer tools. Stdint.h is something that should be installed with the compiler toolchain - to understand further you need to find the compiler error messages. This should be logged somewhere - normally a failed gem extension build will output where it has put the error output
