openssl upgrade fails messily

[Alexy Khrabrov]

I've tried to upgrade git-core today.  It got stuck on openssl in a
messy way, preventing further upgrades:

--->  Computing dependencies for openssl
--->  Fetching openssl
--->  Attempting to fetch openssl-1.0.0a.tar.gz from
http://distfiles.macports.org/openssl
--->  Verifying checksum(s) for openssl
--->  Extracting openssl
--->  Applying patches to openssl
Error: Target org.macports.patch returned: can't read
"configure.sdkroot": no such variable
Error: Unable to upgrade port: 1

~ sudo port upgrade git-core

What do we do in such cases?
