ok ppl found the solution by real trial and error
i looked at the install script and couldn't figure out much except that it was looking for some directories...
so after trying a few times i figured this is what u have to do:
-make a directory called COMMON (uppercase needed) and untar the COMMON.TAR archive there.
-make a directory called LINUXRDR (uppercase needed) and untar the LINUXRDR.TAR archive there.
-KEEP THE COMMON.TAR and LINUXRDR.TAR archives in the installation root directory!
-run ./INSTALL it should work (worked for me)
and once u install it if you're on RedHat 8 like me, it'll give u the following error when u try to start it:
Warning: charset "UTF-8" not supported, using "ISO8859-1".
what you gotta do with this (courtesy http://freshmeat.net/projects/acroba.../?topic_id=112
) is edit the acroread start script and add the line:
LANG=C; export LANG
near the top somewhere
