Yocto: Bitbake not honouring dependencies?

I'm having an issue with a new bitbake recipe. My recipe depends on files produced by a net-snmp recipe from openembedded, but net-snmp doesn't seem to be building before trying to compile my recipe.

In my .bb file, I have:

DEPENDS = " \
        net-snmp \
        ...

EXTRA_OEMAKE += " \
          BINDIR=${STAGING_BINDIR} \
          ...

do_compile() {
    oe_runmake foo
}

Then my makefile includes

CFLAGS=`${BINDIR}/net-snmp-config --cflags` ...

When I run bitbake foo, do_compile throws the error

/bin/sh: [some-path-to-net-snmp-config]: No such file or directory

If I check the staging directory, net-snmp-config is indeed missing. But if I then run bitbake -C compile net-snmp foo, foo builds successfully, and net-snmp-config is in the staging directory.

What am I doing wrong here?

Edit: I've just noticed that even if foo builds successfully, net-snmp is suspiciously absent from my final rootfs image. If I add RDEPENDS="net-snmp" to my recipe, I get the error:

satisfy_dependencies_for: Cannot satisfy the following dependencies for packagegroup-core-boot:
|  *    net-snmp *

I think I found the solution. Based on this blog entry, I added the line

do_compile[depends] += "net-snmp:do_install"

Now my recipe builds successfully every time.

I was also trying to use RDEPENDS incorrectly. Since net-snmp outputs several packages, I needed to specify the individual packages in RDEPENDS in order to include them in my final build.
