Problem building firefox-2.0b1 on Linux

[Subhash Dontireddy]

I'm Trying to build Firefox 2.0 beta1 and I get the following error.

../../dist/lib/libgkconcvs_s.a(nsCanvasRenderingContext2D.o)(.text+0x8a5):

Here is the .mozconfig file.

. $topsrcdir/browser/config/mozconfig
mk_add_options MOZ_OBJDIR=@TOPSRCDIR@/../firefox-build

I've checked with requirements and theses are the ones I got

bash 3.0
gcc 3.4.3
Perl 5.8.7
GNU make 3.80
*No CVS(Do I need it for other than getting the source? I've built
1.5.0.4 without problem.)
widget toolkits.
GTK2 2.8.11(* Building with this option)
GTK 1.2.10
QT 3.3.6 & 4.1.4 (didn't try) with /opt/qt linked to 3.3.6 and
/opt/qt-4.1.4 coming after it in PATH and PKG_CONFIG_PATH
*libXt-devel for X11/Intrinsic.h, X11/Shell.h : Don't know about his
one but locate found the headers in /usr/X11R6/Include, So I guessed
it's okay(Using xfree86 4.5.0 BTW)
libIDL 0.8.6
zip 2.31
freetype 2.1.10
fontconfig 2.3.2
pkgconfig 0.20

Would be glad if any one could help me. I ran out of tricks and ideas.
