Since commit 1841a0eb0d344abf7bd84413807b1e15e3c92496 the rpm-package-build task has been failing (example) because the RPM spec explicitly enables CSFLE and if the required libmongocrypt (version 1.5.0 as of the above commit) is not present then the build fails.

At some point after the release of libmongocrypt 1.5.0 the C driver build will need to be updated to allow the rpm-package-build task to succeed again. This will require monitoring the Fedora package source page to determine when the 1.5.0 release has been packaged and which Fedora releases have included it. It seems likely that releases Fedora 35 and newer should include it. If this is not the case, e.g., only Fedora 36 and/or 37 include the new libmongocrypt, then it will be necessary to adjust the mock chroot target on line 42 of .evergreen/build_snapshot_rpm.sh.
