xorg-dev
x11-dev

I know fedora uses a different system then the debian apt-get program but there should be some similar packages right?

To fix it you need to change a line in Makefile.am.

Change:
xboard_LDADD = -lm @XAW_LIBS@ @GTK_LIBS@
to
xboard_LDADD = -lm @XAW_LIBS@ @GTK_LIBS@ -lXt -lX11

I also had to delete my settings file (~/.xboardrc) which contained settings for my xboard version 4.5.1 for the GTK version to run.
If you need to keep your settings rename this file instead of deleting it.

The GTK version comes up with some warning message boxes at startup, but then it runs OK.
