Hi,

I just applied following patch:
http://cnav.pl/clamav-configure.patch

to clamav sources. And after that libclamav seems to work with pthreads.
ldd /usr/local/lib/libclamav.so.5.4
/usr/local/lib/libclamav.so.5.4:
         Start    End      Type Open Ref GrpRef Name
         084ef000 28522000 dlib 1    0   0 
/usr/local/lib/libclamav.so.5.4
         0d4b9000 2d4bd000 rlib 0    1   0

         091a8000 291af000 rlib 0    1   0      /usr/local/lib/libgmp.so.7.1
         0a04b000 2a12a000 rlib 0    1   0 
/usr/local/lib/libiconv.so.5.0
         02484000 2248d000 rlib 0    1   0      /usr/lib/libpthread.so.11.0
         05a7c000 25a84000 rlib 0    3   0      /usr/lib/libz.so.4.1

Manuals says to use -pthread.
http://www.openbsd.org/cgi-bin/man.cgi?query=pthreads&sektion=3

My question are:
What is the difference between those two libs ?
And why with -lpthread it's working and without not?
