[OT] TTF problem while compiling from source

Hi everyone,
I have a weird problem probably very specific to Fedora, hence who
better to ask but thte list? ;)
I am trying to compile the latest svn trunk of ROOT[1]. It compiles
without errors and everything seems fine. While using the interactive
CLI (known as CINT, its an _interpreter_ for C++), one of the GUIs
segfaults with an error like this:
> Root > Error in <RootX11ErrorHandler>: BadFont (invalid Font parameter) (XID: 54526094, XREQ: 46)
I have reported this to the developers and they haven't been able to
duplicate this problem on their end (on Scientific Linux 4 & 5). Hence
they think this might be something very specific to Fedora. On my system
I have installed everything using yum, so unless there is some
inconsistency somewhere everything should be fine. I haven't seen any
other font problems in any of the apps I use. So kinda stumped how to
troubleshoot this.
This is what one of them had to say about the problem,

(he made the last comment since I had mentioned I have used yum for
everything)
Now what would be the packages I should be looking at for this? I tried
`yum search ttf' but that only comes up with fonts. Is there some
package that controls how fonts behave in general? I have heard of
fontconfig and something about ROOT not using fontconfig[2] but I don't
know whether that is relevant here.
This framework is like bread and butter for me, so pointers to where I
should look to get behind all this will be very helpful. Thank you in
advance for any suggestions.
