is this the software?
and did you download it from google code ?
you will need to build that SOURCE CODE
and for that you will NEED to buy the redhat Support contract / license
redhat is NOT free
migrate to the FREE CentOS 6.5
you will need to install the gcc compiler and a bunch of software needed to build that code
--- this will take a lot of time !!!
you will need to first learn HOW to build the software
first extract the contencs of the archive " qGTalk_en-0.5.1.tar.gz"
in the folder there is a file called README ( yes just like Alice with "eatme" and "drinkme" this is README )
and read the INSTALL file
these are the instructions
seeing as this is a QT project the normal
DOSE NOT apply
there is a file called "qGTalk.pro"
this is used by the program "qmake"
qmake needs to be installed
for that you will need to have access to the redhat RHN software repo
( a registered licensed install of RHEL -- ie a paid for install )
be using the free CentOS 6.5
