Same here:

Looking up update.FreeBSD.org mirrors... 5 mirrors found.
Fetching metadata signature for 10.1-RELEASE from update5.freebsd.org... done.
Fetching metadata index... done.
Fetching 2 metadata patches.. done.
Applying metadata patches... done.
Inspecting system... done.
Preparing to download files... done.
Fetching 8 patches..... done.
Applying patches... done.
Fetching 461 files... done.

The following files will be removed as part of updating to 10.1-RELEASE-p2:
/

The following files will be added as part of updating to 10.1-RELEASE-p2:
/libexec/ld-elf32.so.1
/usr/bin/ldd32
/usr/lib32/Scrt1.o
/usr/lib32/crt1.o
/usr/lib32/crtbegin.o
/usr/lib32/crtbeginS.o
/usr/lib32/crtbeginT.o
/usr/lib32/crtend.o
/usr/lib32/crtendS.o
....

Why all lib32 are needed for amd64 now??
