The Greens won the game with a well-worked goal from experienced striker Ahmed Osman after defender Harrison Afful hesitated.
Midfielder Ibrahim played in Osman with a clever pass which Afful failed to clear and the 30-year-old slotted the ball into the net from an acute angle with only four minutes remaining.
The win took Libya to the top of the group with 12 points, leaving the Black Stars second on nine points.
Ghana had numerous scoring chances in the first half but Junior Agogo and Sulley Muntari fluffed the opportunities after key midfielder Michael Essien was taken off injured.
The Chelsea player was substituted with what looked like a serious injury midway through the first-half after being cynically hacked down.
He was replaced by captain Stephen Appiah, who was making his first appearance in a competitive match after a nine-month injury-induced absence.
The former Fenerbahce midfielder didn't look rusty as Agogo and Muntari failed to utilise his inch-perfect passes.
Ghana must beat Lesotho at home in their final match in October if they are to stand any chance of advancing to the second phase of the qualifiers.
A draw for Libya in Gabon in October will see them topping the group.
Gabon are in third with six points, but are expected to make headway on Sunday when they take on pointless basement dwellers Lesotho.
