This is a good point, of course, and we often find that printers neglect the replacement of old tubes in their light booths or even substitute ordinary fluorescents. Print buyers need to be aware of this issue as well as install and use print viewers in their own offices.
For fine-art exhibition printing such as you're doing it makes some sense to account for gallery lights in your profile, but be sure that it's general enough to make the prints look good in most settings. Accounting for halogen gallery lights is one thing--they have a smooth spectral power distribution so it's mainly a matter of "cooling" the print with a white point edit. On the other hand I would avoid using any adaptation for fluorescent lighting, even if these are present (as they often are in public venues) since these sources have rather spiky output that can vary quite a lot by brand and model and you can end up with prints that may be unusable in most situations.

How many publications are actually read in quality lighting conditions, as opposed to the light of a cheap CFL at home or economy fluorescent tubes at the office? Not to mention, of course, all the strongly-colored objects (like clothes) we humans tend to surround ourselves with.

For example, I had some prints shown at the Tempe Public Library, and I was able to make a custom profile based off a spectrophotometer measurement of the actual gallery lighting. Amazingly enough, test prints showed that the gallery versions looked muddy in sunlight but great in the gallery lighting, and D50 versions were the exact opposite. Go figure....)
