Problems installing 6.0-BETA4: syntax error

Tested the 6.0-BETA4 CD install on the folowing system:

- P4 at 3,0 GHz.
- P5GD1 motherboard (ICH6-R controller).
- 1 GB of memtest-checked RAM.
- Two 200GB Maxtor 6B200M0 BANC1980 SATA 150 drives.
- LG DVD+-RW (HL-DT-ST DVDRAM GSA-4160B/A300).

This same system experienced another more serious problem with BETA3 CD, 
which seems fixed now ("Write failure on transfer!").

The first anomaly is that there are eight "acpi_bus_number: acn't get 
_ADR" messages in dmesg.

And the #109 LOR appears each time while extracting distributions from 
CD to disk (not before that):

Trying to mount root from ufs:/dev/md0
lock order reversal
1st... UMA lock _at_ /usr/src/sys/vm/uma_core.c:1494
2nd... system map _at_ /usr/src/sys/vm/vm_map.c:2317

The install finishes successfully (though the LAN adapter is not 
recognized) unless you install X11. Then, when installing the fontconfig 
package, a syntax error appears:

"Add of package fontconfig-2.2.3,1 aborted, error code 1"

The debug screen shows the following:

rescue/librescue/Makefile

ldconfig: warning: /usr/local/lib: No such file or directory
ldconfig: warning: /usr/X11R6/lib: No such file or directory
