Cannot run the quartus 9 on CentOS 5.4

does it refer to a line number? i would like to check this out.

[root@localhost Altera Software]# ls

something strange there, it looks like its installed already. i just grabbed 9.1-linux-free and here's my ls:

$ ls
adm.gz        dev_info.txt    ip_lic.txt    md5sum.txt   stub.csh
agx_we.gz     devinfo_we.gz   libraries.gz  perlsrc.gz   stx2_we.gz
aii_we.gz     dsp_builder.gz  license.txt   qcleanup     stx3_we.gz
common.gz     eda.gz          linux.gz      qdesigns.gz  stx4_we.gz
compare       gpl_lic.txt     lmf.gz        qt           stx_we.gz
cusp.gz       gtar            m3k_we.gz     readme.txt   sys_reqs.txt
cyc3_we.gz    gzip            m7ka_we.gz    sgxii_we.gz  tutorial.gz
cyc4gx_we.gz  help.gz         m7k_we.gz     sgx_we.gz    version.txt
cycii_we.gz   install         manifest.txt  sopc.gz
cyc_we.gz     ip.gz           maxii_we.gz   space.txt

and ./install opens up the install script and prompts me for install location. this is on Fedora 12.

Forgot to mention i'm trying to install quartus 7.1 (it came along with the DE2-70 board... it supports stratix devices i intend to use, which is not the case for the webpack version).

the current script has that same line so i'm not sure that's the problem.
