Thinstation 2.1 lacks the dirname binary, which means we have to use some special hacks to run the client. Currently, /bin/thinlinc and /bin/thinlinc-console sets TLCLIENT_PREFIX and runs tlclient.bin directly instead of using the ordinary 'tlclient' script. Also, the tlcontrol script is adapted to use TLCLIENT_PREFIX. Miles Roper has promised that dirname will be in Thinstation 2.2rc2 (and I've promised him some icecream if we meet, he says he'd like his with choc chips and some nuts), which means that when TS 2.2 is released we can remove the TS-specific hacks and make TS 2.2 a requirement for the ThinLinc thinstation package. See also komintern text 249293.
TS 2.2 has been released as of 2006-10-16, so the prerequisites for this bug is now in place.
