>Description:
On Solaris, pkg_install uses libnbcompat to get (among other things) MD5File.
It appears that when this is used there are no prototypes for MD*(), thus 
the return value of these is assumed to be int, and in a 64bit environment
that does not work as MD5File returns a char * and it gets truncated.
 
The nbcompat/md5.h include was removed in 1.40 of nbcompat.h, stating an 
incompatability with openssl headers; I'm not sure what the right solution 
is.
>How-To-Repeat:
Build the bootstrap and run pkg_delete.
