How can I make Lightroom use a specific lens profile?

In Lightroom 4 on Mac OS X, I’m trying to apply a downloaded lens profile for a Rokinon/Samyang/Bower 14mm f/2.8 used on a Canon 6D. It used to appear in the Lens Corrections panel and apply when I chose Canon as the make, but now Lightroom defaults to a Canon 15mm f/2.8 profile and the custom profile no longer appears in the Profile list.
How does Lightroom decide which profiles appear in the list, and is there any way to force Lightroom to use a particular profile if it isn’t being shown?

Lightroom uses the make and the model of the lens to filter the list of displayed profiles, as determined from the EXIF data or selectable from the drop-down lists, as well as the file type (RAW or JPEG). you can see (and edit, if you are adventurous) these parameters n the .lcp files, i've successfully used a profile created for JPEG for my RAW's. (this, of course, is only advisable if your camera does not perform any in-camera lens corrections to the JPEG's).
Those .lcp profiles are just XML files, so you can edit them with any text editor. There's a line <stCamera:CameraRawProfile>False</stCamera:CameraRawProfile> where Falsemeans a JPEG profile, and True raw.

Lightroom filters available lens profiles using metadata in the image and metadata inside the .lcp profile itself. The main factors are lens make/model, camera, and whether the profile is marked for RAW or JPEG.
So if your custom Rokinon profile no longer appears, Lightroom likely no longer considers it a match for that file. That’s why it shows only profiles it thinks fit, such as the Canon 15mm profile.
You generally can’t simply force an unavailable profile from the normal dropdown if Lightroom has filtered it out. However, .lcp files are XML text files, so advanced users can inspect or edit the profile metadata to make it match the camera/lens/file type Lightroom is looking for. One important field is whether the profile is for RAW or JPEG.
If you edit anything, make backups first. Also, using a JPEG profile on RAW files is only sensible if your camera is not applying in-camera corrections to the JPEGs.
In short: Lightroom’s profile list is metadata-driven, and the practical workaround is to check or edit the .lcp file so its camera/lens/RAW-JPEG flags align with your images.
