Rich dependency failure or PEBCAK?

[brianjmurrell]

If I have a BR (line only broken below for clarity, it's all one long line the actual spec file):

BuildRequires:  (pkgconfig(ffnvcodec) >= 12.1.14.0 or
                 (pkgconfig(ffnvcodec) >= 12.0.16.1 and pkgconfig(ffnvcodec) < 12.1) or
                 (pkgconfig(ffnvcodec) >= 11.1.5.2 and pkgconfig(ffnvcodec < 12.0) or
                 (pkgconfig(ffnvcodec) >= 11.0.10.3 and pkgconfig(ffnvcodec < 11.1) or
                 (pkgconfig(ffnvcodec) >= 8.1.24.15 and pkgconfig(ffnvcodec < 8.2))

and I have installed nv-codec-headers-11.1.5.2-1.el9.noarch which provides:

nv-codec-headers = 11.1.5.2-1.el9
pkgconfig(ffnvcodec) = 11.1.5.2

shouldn't the above BR: allow the build to happen?

I'm actually getting:

Error: 
 Problem: nothing provides requested (pkgconfig(ffnvcodec) >= 12.1.14.0 or (pkgconfig(ffnvcodec) >= 12.0.16.1 and pkgconfig(ffnvcodec) < 12.1) or (pkgconfig(ffnvcodec) >= 11.1.5.2 and pkgconfig(ffnvcodec < 12.0) or (pkgconfig(ffnvcodec) >= 11.0.10.3 and pkgconfig(ffnvcodec < 11.1) or (pkgconfig(ffnvcodec) >= 8.1.24.15 and pkgconfig(ffnvcodec < 8.2))
(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)

As an aside, is there any way to actually break long lines like the above in a specfile? Can I use \ for example?
