Odd... What version of gcc is this? Mine (4.1.2) compiles it just
fine... Does this compile for you?
#define libFLAC_is_present 1
#define libFLAC_symbol_is_present(sym) 1
#include <stdio.h>

int main() {
        int bah=331;
        if (libFLAC_is_present)
                printf("lib_is_present worked\n");
        else
                printf("lib_is_present failed\n");

        if (libFLAC_symbol_is_present("foobar"))
                printf("symbol_is_present worked\n");
        else
                printf("symbol_is_present failed\n");
        return 0;
}

What's the exact error from gcc about not linking the parens?

However, having relaytool installed won't/shouldn't end up affecting
anything (or soft-linking anything) because relaytool doesn't work on
Macs/Windows systems.
