[Mono-list] mono installation problem on RedHat9

[Ivan Turcan]

Hello Friends,

I am trying to install Mono 1.0 Release: Red Hat Linux 9.0, x86 . I have 
downloaded zip file mono-all.zip which contains lot of RPM files. but have 
problem that when i try to
install some rpm, i have this error message:

for example i execute: rpm - i mono-ms-enterprise-1.0-1.xmian.6.1.i386.rpm
and result i get:
error: mono-ms-enterprise-1.0-1.xmian.6.1.i386.rpm: rpmReadSignature failed: 
region trailer: BAD, tag 15872 type 2047 offset 20480 count 4096
error: mono-ms-enterprise-1.0-1.xmian.6.1.i386.rpm cannot be installed

could somebody help me how to install mono on RedHat9 ? it's possible ? or 
need i choose different linux distribution ?

many thanks for help
