Maestro depends on mdbtools for extracting part data from a Parts&Vendors database. I have always used mdbtools on FreeBSD (installing the binary package), but recently have needed mdbtools on Centos 7 for use with ERPNext. I read a number of internet posts recommending installing mdbtools from the Fedora EPEL repository but, if mdbtools is still in EPEL, I need to learn more about installing software on Centos/RHEL.
Except for installing a few pre-requisites, install generally followed the mdbtools github README.mdb.
# yum install glib2-devel
# yum install txt2man
# yum install gnome-doc-utils
# cd /root/work
# git clone https://github.com/brianb/mdbtools.git mdbtools
# cd mdbtools
# autoreconf -i -f
# make install
The mdbtools utilities are installed to /usr/local/bin/
Each utility has its own man page
# man mdb-export
and includes built-in short help
