problems around update

Dear friends,

I using you because, in lists and forums, I don't found the solution for my
problem:

In the weekend, I stated update of my system hoping to solve problems around
apci and boot.

I use csup and the usual procedures for update the system:

cd /usr/src
csup -L2 -g /usr/loca/etc/src-supfile
make buildworld
make buildkernel KERNCONF=MKern
make installkenrel KERNCONF=MKern
mergemaster -p
make installworld
mergemaster -Pi

Will normally if I get the current sources, but that was not the case.

I invoke incorrect supfile:

**default host=cvsup2.br.freebsd.org
*default base=/var/db
*default prefix=/usr
*default release=cvs tag=RELENG_7

*default delete use-rel-suffix

*default compress

src-all*

When must call this:

**default host=cvsup12.FreeBSD.org <http://cvsup12.freebsd.org/>
*default base=/var/db
*default prefix=/usr
*default release=cvs tag=.

*default delete use-rel-suffix

*default compress

src-all*

Some problems bega to appear.

# mergemaster -Pi

*** Beginning comparison

/libexec/ld-elf.so.1: find: Undefined symbol "fts_open"

# find ./ -name "ath*"
/libexec/ld-elf.so.1: find: Undefined symbol "fts_open"

When repair the sources via csup, I received this error message:

csup -L2 -g /usr/local/etc/current
supfile
(10-28 12:42)
/libexec/ld-elf.so.1: /lib/libthr.so.3: version FBSD_1.1 required by csup
not found

And, during process to recompilation of the kernel, the same message is
printed:
# make

Ok, ok. I'm a stupid
Any suggestions to solve it?
