Like the comment said, in the case of a single space, you can just hard code it. If you need to be more flexible or tolerant:
I'd use a skipper with raw
to "cheat" the skipper for your purposes:
bool const r = qi::phrase_parse(b, e,
qi::raw [ *(qi::char_ - qi::char_("(")) ] >> qi::lit("(Spirit)"),
qi::space,
parsed
);
This works, and prints
PASSED:
Parsed: "Fine"
Rest: ""
PASSED:
Parsed: "Hello, World"
Rest: ""
See it Live on Coliru
Full program for reference:

#include <string>
#include <iostream>
namespace qi = boost::spirit::qi;
using std::string;
using std::cout;
using std::endl;

test_input(const string &input)
{
string::const_iterator b = input.begin();
string::const_iterator e = input.end();
string parsed;
bool const r = qi::phrase_parse(b, e,
qi::raw [ *(qi::char_ - qi::char_("(")) ] >> qi::lit("(Spirit)"),
qi::space,
parsed
);
if(r) {
cout << "PASSED:" << endl;
} else {
cout << "FAILED:" << endl;
}
cout << " Parsed: \"" << parsed << "\"" << endl;
cout << " Rest: \"" << string(b, e) << "\"" << endl;
}
int main()
{
test_input("Fine (Spirit)");
test_input("Hello, World (Spirit)");
return 0;
