Barred from making chords

There was a quote on the show Buffy the Vampire Slayer many moons ago that really struck a chord with me. Oz (as played by Seth Green) had a conversation with one of his band mates

Devon: Man, we need a roadie. Other bands have roadies.
Oz: Well, other bands know more than three chords. Your professional bands can play up to six, sometimes seven completely different chords.
Devon: That's just, like, fruity jazz bands.

For me it goes beyond simply not being able to play a lot of chords. I can play a lot of chords however I still have issues with barre chords. A barre chord will have a construction similar to this:

e----5--------
B----5--------
G----6--------
D----7--------
A----7--------
E----5--------

Whereas your standard (and my staple) 5th chord would consist of the top 3 notes (actually the bottom if you're looking at the tab above) a barre chord will use every string. Oddly my issues is with the same string every time. The occursed B string. Unfortunately I have severely limited flexibility in my fingers. If others are double-jointed, I'm half-jointed. The little crease behind the knuckle of my pinky gives the B string just enough play so that it doesn't press against the frets. For those not guitar-savvy that means instead of a *DING* of a note I get the *DUNK* of a dead-note. so my barre chords look more like this:

e----5--------
B----x--------
G----6--------
D----7--------
A----7--------
E----5--------

This is really screwing me up on "Yellow Led Better" by Pearl Jam which is an awesome guitar song, awesome song all around and as a bonus not that difficult to sing. Even on my ESP F-50 (which has a pretty low action) I still can't make this chord properly. Alas I guess practice makes perfect so it'll have to be back to the drawing board.

we will we will rock you
