Obviously, this is a recipe that you made.

Does it show these dependencies?  e.g. a line like this in your recipe file:
   DEPENDS = "net-snmp fuse"
(or whatever the *packages* that you need are)

Bitbake can't read your mind; it will only build the recipes you ask and the
dependencies which are explicitly specified in that build chain.

If you still have trouble, try sending your recipe (.bb file and all other
components you might have), bblayers.conf, etc to the list because we're not
mind readers either :-)
