-lpthread problem?

[Anthony Green]

I have a gcj-based application on Linux which links in a number of
third-party shared libraries, all created with libtool.  One of these
libraries was itself linked with -lpthread.

I have discovered that my application hangs while getting a stack trace
unless I remove the -lpthread from the link line of the library I link
into my application.

I think this would really baffle a casual user.  Any suggestions on how
to make it a little more friendly?
