RHEL OS specific issue with Zlib #710
Description
I'm just posting this in case somebody else runs into this as I didn't see any viable results with google.
System is AlmaLinux 9 (RHEL9)
When the RPM perl-Compress-Raw-Zlib-2.101-5.el9 is installed you will get the version conflict when trying to run MailScanner.
Trying to remove the rpm will lead to dependency hell.
Zlib installed through CPAN, that I think ms-configure installed, is ignored:
MailScanner --lint
Compress::Raw::Zlib version 2.214 required--this is only version 2.101 at /usr/local/share/perl5/5.32/Compress/Zlib.pm line 11.
BEGIN failed--compilation aborted at /usr/local/share/perl5/5.32/Compress/Zlib.pm line 11.
Compilation failed in require at /usr/share/MailScanner/perl/MailScanner/SA.pm line 34.
BEGIN failed--compilation aborted at /usr/share/MailScanner/perl/MailScanner/SA.pm line 34.
Compilation failed in require at /usr/sbin/MailScanner line 107.
BEGIN failed--compilation aborted at /usr/sbin/MailScanner line 107.
The solution:
The RPM has its files in:
/usr/lib64/perl5/vendor_perl/auto/Compress/Raw/Zlib/Zlib.so
/usr/lib64/perl5/vendor_perl/Compress/Raw/Zlib.pm
The CPAN files are in:
/usr/local/share/perl5/5.32/Compress/Zlib.pm
/usr/local/lib64/perl5/5.32/auto/Compress/Raw/Zlib/Zlib.so
What I ended up doing is just renaming the RPM files. Perl then seems to automatically pick up on the CPAN files instead.
I am somewhat doubting there will be an update to the RPM but you never know.
I've not rpm -e --nodeps'd it but I might try if it's a future me problem. So far everything seems to be running just peachy.
I also believe this goes for RHEL 10, as that also has a version lower than 2.214 (2.212 I think)
I'm not sure if the RPM was installed because of something I did in the past or not but it's there and it's annoying to get rid of.
