Issues with installing EPrints on RHEL / CentOS / Rocky 8

elinks package longer available

The RPM package elinks is no longer available in RHEL 8. elinks is probably no longer needed so if installing from source use the following YUM command line:

yum install libxml2 libxslt httpd mod_perl perl-DBI perl-DBD-MySQL perl-IO-Socket-SSL perl-Time-HiRes \
    perl-CGI perl-Digest-MD5 perl-Digest-SHA perl-JSON perl-XML-LibXML perl-XML-LibXSLT perl-XML-SAX \
    perl-LWP-Protocol-https perl-MIME-Lite perl-Text-Unidecode tetex-latex wget gzip tar ImageMagick \
    poppler-utils chkconfig unzip

Compatibility issues with XML::LibXLST

Sometimes the Perl module XML::LibXLST packaged in the perl-XML-LibXSLT package causes segmentation faults with the Apache httpd webserver. Therefore, it may be better to install this Perl module using CPAN (as the root user):

yum purge perl-XML-LibXSLT
cpan XML::LibXSLT

Missing Perl modules

There are a number of perl Modules that EPrints requires that are not available through the standard (inc. EPEL) Yum repositories, these can be installed through CPAN:

cpan TeX::Encode 
cpan YAML
