OK you're right, i should be more precise what bitbake/bbclasses do.
But first I was refering to build-time dependecies where we would sometimes
need to add something like ie "DEPENDS => qt4-x11-free_4.6" and make
bitbake to emit error if someone has PREFERRED_VERSION_qt4-x11-free =
"4.5.2" and tries to build recipe with this dependency.

Yes it's mostly in package.bbclass package-ipk.bbclass.

Package names from RDEPENDS are modified on their way to "Depends:" in
opk file, because RDEPENDS has to refer to existing name in PACKAGES
varible of some other recipe and this recipe is build as dependency (to
make sure that it will be available in feeds when user install package
depending on that.
But package name in PACKAGES isn't the same what opkg see, its also
modified on its way and you can even specify how, ie in shr.conf we have
# libfoo -> libfoo0-2 (etc)
INHERIT += "debian"
Example:
in dillo2_2.1.1.bb is RDEPENDS = "fltk2-images"
in fltk2_svn.bb is PACKAGES =+ "${PN}-fluid ${PN}-images"
but the resulting file is named
libfltk2-images_1.9.9+svnr6916-r1.4_armv4t.ipk
and "Depends:" fields is expanded with other dependencies and package
names are "fixed" like this
Depends: libfltk2-images, libc6 (>= 2.10), libjpeg62 (>= 6b), libpng12-0
(>= 1.2.41), libz1 (>= 1.2.3), libfltk2-2.0 (>= 1.9.9+svnr6916),
libx11-6 (>= 1.3.2), libxi6 (>= 1.3), libxinerama1 (>= 1.1), libxcursor1
(>= 1.1.10), libxft2 (>= 2.1.14), libxext6 (>= 1.1.1), libstdc++6 (>=
4.4.2), libgcc1 (>= 4.4.2)
RCONFLICTS isn't expanded so much, but runtime renaming is still needed
For bzip2 issue I tried
RCONFLICTS_libbz2 = "'bzip2 (<= 1.05-r0.4)'"
and
RCONFLICTS_libbz2 = "bzip2 (<= 1.05-r0.4)"
First ends with
Conflicts: bzip2, (<=, 1.05-r0.4)
Because before writting it to Conflicts: it's splitted and then ", ".joined,
but it goes OE through explode_deps
<debug>
NOTE: RCONFLICTS before: bzip2 (<= 1.05-r0.4)
NOTE: explode_deps: bzip2 (<= 1.05-r0.4) before
NOTE: explode_deps: ['bzip2 (<= 1.05-r0.4)'] after

NOTE: rconflicts: ['bzip2', '(<=', '1.05-r0.4)'] - bzip2, (<=,
1.05-r0.4)
</debug>
and the second
Conflicts: 'bzip2
Killed in explode_deps
<debug>
NOTE: RCONFLICTS before: 'bzip2 (<= 1.05-r0.4)'
NOTE: explode_deps: 'bzip2 (<= 1.05-r0.4)' before

NOTE: RCONFLICTS after: 'bzip2

NOTE: rconflicts: ["'bzip2"] - 'bzip2
</debug>
I'm not OE/bitbake guru (or even python programmer) to fix this issue in
bbclasses and as you can see it's not as easy as it seems to be. Also if
there is some easy way I guess it would be already used in OE recipes.
But if you create patch, which will work for all OE-possible
combinations, then I guess it will be really welcome.
In attachment is what I used for additional debug info, in case someone wants to
do his homework too :).
