FreeType is apparently not installed

[frimbas]

Under Quickinstaller får jeg denne besked!

"FreeType is apparently not installed
It looks like the FreeType library is not compiled into GDLib. This is required when TYPO3 uses GDLib and you'll most likely get errors like 'ImageTTFBBox is not a function' or 'ImageTTFText is not a function' "

Jeg har fundet FrerType og lastet ned, og pakket ut filer og mapper, men hvor og hvordan laster jeg det op?
