In x11-plugins/wmnd ebuilds (versions 0.4.11-r1 and 0.4.13) is net-analyzer/net-snmp defined as build dependecy only (DEPEND). However wnmd binary requires libsnmp to _run_ if build with snmp support. ldd /usr/bin/wmnd ... libsnmp.so.15 => /usr/lib/libsnmp.so.15 (0x00007fe8677c9000) ... Definition of the snmp dependency should be moved to RDEPEND.
Thanks for reporting this issue, assigning to maintainers.
Fixed (and wiped out oldest version).
