You were pretty close, just the message is to long (max. 32) and you need to quote differently:
Quote:$ echo -n "This is a long salt" | openssl dgst -sha1 -hmac "key"
(stdin)= ea801b719276e06d8cb971860e2958db924e7dc9
Quote:$ ./oclHashcat64.bin -m 150 -a 3 "ea801b719276e06d8cb971860e2958db924e7dc9:This is a long salt" ?l?l?l

ATTENTION!
The wordlist or mask you are using is too small.
Therefore, oclHashcat is unable to utilize the full parallelization power of your GPU(s).
The cracking speed will drop.
