I have seen many posts relating to this type of issue but no canonical way to fix it properly.
Since updating to F23 (from F22) using dnf last night, many/all PERL programs are broken and give errors such as:
fetch_modules: error loading required module Compress/Zlib.pm: Can't load '/usr/local/lib64/perl5/auto/Compress/Raw/Zlib/Zlib.so' for module Compress::Raw::Zlib: libperl.so.5.20: cannot open shared object file: No such file or directory at /usr/lib64/perl5/DynaLoader.pm line 193. at /usr/local/share/perl5/Compress/Zlib.pm line 11. Compilation failed in require at /usr/local/share/perl5/Compress/Zlib.pm line 11. BEGIN failed--compilation aborted at /usr/local/share/perl5/Compress/Zlib.pm line 11. Compilation failed in require at /usr/sbin/amavisd line 210. /usr/bin/perl: symbol lookup error: /usr/local/lib64/perl5/auto/MIME/Base64/Base64.so: undefined symbol: Perl_xs_version_bootcheck
or
-- /usr/bin/perl: symbol lookup error: /usr/local/lib64/perl5/auto/Unix/Syslog/Syslog.so: undefined symbol: Perl_xs_version_bootcheck
I understand from other posts that this is probably caused by my having two PERL installations but:
a. I have no idea why there are two PERLs b. I can find no instructions on how to remove one version and (hopefully) fix this issue.
(In the meantime, I cannot run amavisd so am inundated with spam.)
TIA, Stephen
