In the official manual http://weitz.de/drakma/#connection-timeout connection-timeout key parameter exists. But my SBCL interpreter says:

debugger invoked on a SB-INT:SIMPLE-PROGRAM-ERROR:
unknown &KEY argument: :CONNECTION-TIMEOUT

Type HELP for debugger help, or (SB-EXT:QUIT) to exit from SBCL.

restarts (invokable by number or by possibly-abbreviated name):
0: [ABORT] Exit debugger, returning to top level.

(DRAKMA:HTTP-REQUEST "http://bcheck.scanit.be/bcheck/")[:EXTERNAL]
0]

when I try to call function:

(drakma:http-request "http://bcheck.scanit.be/bcheck/"
:method :get
:content-length t
:connection-timeout 10)

Please help me to solve this problem.

Best regards,
