Mono compiler error

[Ivan Voras]

I tried the recently-released Mono (ports/lang/mono), and as far as I 
can see, things work, EXCEPT when I try to compile monodoc (get 
http://mono2.ximian.com/archive/1.0/monodoc-1.0.tar.gz, unarchive, 
./configure, make), where I get this error:

mcs -debug -out:browser.exe ./browser.cs                 ./list.cs 
         ./elabel.cs              ./history.cs 
./Contributions.cs      ./XmlNodeWriter.cs 
-resource:./../monodoc.png,monodoc.png 
-resource:./browser.glade,browser.glade  -pkg:gtkhtml-sharp 
-pkg:glade-sharp -r:System.Web.Services -r:./monodoc.dll
Assertion failed: (lu->lu_myreq->lr_owner == lu), function 
_lock_acquire, file /usr/src/lib/libpthread/sys/lock.c, line 171.
Abort trap (core dumped)

This is on a system from 2004-07-14.
