gpgme not compiling when gpgsm support disabled

[Jason E. Hale]

I tried to compile gpgme-1.2.0 on FreeBSD 8.0 with the following configure 
arguments:
--with-gpg=/usr/local/bin/gpg2 --with-gpgsm=no --with-
gpgconf=/usr/local/bin/gpgconf

The build stops because it cannot find assuan.h.

I removed the #include "assuan.h" line from engine-gpgconf.c and the build 
succeeded.  Is the include neccessary?  Is libassuan needed for gpgconf 
support or only gpgsm?  I am not subscribed to the list...please CC me.

Thanks,
Jason
