Need help in compiling firefox on ubuntu 7.10

[yinglcs2]

Hi,

I am trying to compile firefox 2.0.0.11 on ubuntu 7.10. And I am getting the following error while linking.

I have checked that my LD_LIBRARY_PATH has /usr/lib
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib:/usr/lib:

And I do have

$ pwd
/usr/lib
$ ls -la libXt*
-rw-r--r-- 1 root root 429164 2007-05-21 07:27 libXt.a
lrwxrwxrwx 1 root root 14 2007-10-18 17:06 libXt.so -> libXt.so.6.0.0
lrwxrwxrwx 1 root root 14 2007-10-18 17:06 libXt.so.6 -> libXt.so.6.0.0
-rw-r--r-- 1 root root 326564 2007-05-21 07:27 libXt.so.6.0.0

Can you please tell me how can I resolve my problem?
