Lens profile exists, shown in Library but not in Develop

Hi - I recently took some photos in my Pentax K5 in full auto mode, and they are thus all JPG.
In Lr in the Library module, the lens information is correctly shown, but in the Develop module, unlike with DNG files, it has to be selected manually.
However, the lens (an smc DA) is not in the available lenses list, indeed no smc lenses appear in the list.
How to I get my smc lens into the list?
Screen shots below:

Library module, correct lens shown:

Develop module, no smc lenses in list:

Most lens profiles are only for raw files. Very few profiles exist for jpeg files. What is shown in the Library is not the profile, but simply which lens you used. That info is recorded in the metadata.

For fellow sufferers here is a link showing you how to create JPG lens profiles:

On a Mac the Adobe lens and camera profiles are well hidden:
Applications/Adobe Photoshop Lightroom X/Right-click Show Package Contents/Resources/Camera Profiles
Applications/Adobe Photoshop Lightroom X/Right-click Show Package Contents/Resources/Lens Profiles

Save your custom lens and camera profiles in the Library (hold down Option then choose Library from the Go menu in Finder to see these folders)

Actually the instructions in the link above are not correct. This is how I got it to work.

1. Copy the required lens correction file from Applications/Adobe Photoshop Lightroom X/Right-click Show Package Contents/Resources/Lens Profiles to Library/Application Support/Adobe/CameraRaw/LensProfiles/Pentax
2. Rename the file dropping the RAW ending: e.g. PENTAX (smc PENTAX-DA 18-135mm F3.5-5.6 ED AL[IF] DC WR) - RAW.lcp becomes PENTAX (smc PENTAX-DA 18-135mm F3.5-5.6 ED AL[IF] DC WR).lcp
3. Open the file in text editor and unlock
4. Use Edit | Find to locate and DELETE the tag <stCamera:CameraRawProfile>False</stCamera:CameraRawProfile>
5. Use Edit | Find | Find and Replace to replace the string CameraRawProfile="True" with CameraRawProfile="False"
6. Save the file and relaunch Lightroom.
