Hi,

I was also bitten by this. I'm sharing how I got past the issue in case 
it could be useful to others.

I recovered by rolling back to a previous ZFS snapshot using an USB 
installation media. This can be a viable solution depending on FS being 
used and availability of snapshots.

Anyway, after taking the machine to a usable state I was able to update 
past the tripping point by doing:

pkg-static upgrade -r <base-repo> -g 'FreeBSD-runtime*' 
'FreeBSD-pkg-bootstrap*' 'FreeBSD-clibs*'

(the bootstrap part is most probably not needed)

this will tell you it wants to remove the pkg package, but will not do 
so, since there is no '-f' option. After this proceed with a `pkg-static 
-r <base-repo> upgrade`.

Depending on how old the previous installation is you will need to check 
for new packages to install, I was missing a bunch -dev and -man ones, 
and some new ones.

I then had to add this to libmap.conf (actually to 
/usr/local/etc/libmap.d/upgrade.conf):

libcrypto.so.30 libcrypto.so.35
libutil.so.9 libutil.so.10
libssl.so.30 libssl.so.35


So old ports depending on old libraries still work. I'm keeping these 
for a while, until I can perform a `pkg upgrade -f`


Hope this can be helpful until the issue is solved.
