It appears the syslog-ng38epel6 on COPR uses libdbi 0.9.0 from el7.  When attempting to install syslog-ng from here, on an CentOS 6 instance, and then install libdbi-dbd-mysql, yum is unable to find appropriate version of libdbi-dbd-mysql to install.  On el6, only libdbi 0.8.3 appears to be available, which yum does not think is compatible with libdbi 0.9.0.  Not sure how to use syslog-ng's mysql destination on CentOS/RHEL 6 due to this.  Any insight how to solve this, without creating a separate copr/obs build, would be appreciated !
