Upgrade libXt-devel

[Jose Rodriguez]

Hi everyone!

I have the following problem: im downloaded ns-allinone-2.33 (network
simulator) and while it is installing i get the following error

*checking for X11 header files
can't find X includes
otcl-1.13 configuration failed! Exiting ...
Please check http://www.isi.edu/nsnam/ns/ns-problems.html
for common problems and bug fixes.
*
Searching online i found this

*It is looking for /usr/include/X11/Intrinsic.h, which is in the
libXt-develpackage.
*
*You can try installing that package, but it (and libX11-devel) should have
been installed as part of the "X Software Development" group. I guess you
didn't install that whole thing. I always install all development tools,
including all of the optional packages, when creating a new Linux system.*

My question is, how do i upgrade or reinstall that library or the X Software
Development??? Im not sure if what i found applies for Ubuntu b/c after that
he suggests to use "yum" to update the library while we can use apt-update
or aptitude or synaptic.

Hope to hear from you soon
Thanxs everyone
