We don't have much context for the occurrence of that 5.3.0 install
error, so can't offer much advice except to assure that you have all
the right filesets, and that they are intact (particularly meaning,
that if you FTPed them, that you did so in Binary mode).  liblpp.a is
generally a lib file which comes embedded in the install package, and
which installp uses to proceed with the installation.  It's absence
indicates that stuff is somehow missing.  Whereas the Subject line of
this posting is unrelated to the error you are reporting, the
platform on which you are installing is unclear.  If AIX, assure
that /usr has plenty off space to support the installation of new
software: committing previously installed software is one way of
getting back some space in /usr.  Whereas probably hundreds of
customers have installed TSM 5.3 without encountering this error, it
would seem that there is something fundamentally wrong in your
environment contributing to this problem.  I would advise reviewing
the install instructions - very much including the Readme file - and
assure that all steps are being performed, assuring no errors in any.
