DBMS_STATS/DBMS_STATS_INTERNAL won't recompile without errors.

Question

I'm trying to drop and recreate the AWR in an Oracle 11.1.0.7 database. Per instructions, I started the database with statistics_level set to BASIC to turn off AWR/ADDM and then ran:
@?/rdbms/admin/catnoawr.sql -- to drop the AWR structures -- it ran fine.
@?/rdbms/admin/catawrtb.sql -- to rebuild the AWR structures -- it ran fine, too.
I tried to run a manual snapshot in the database and it errored saying that the package
SYS.DBMS_STATS was invalid. I ran the following to recompile the procedures but received
the following error:
Warning: Package created with compilation errors.
SQL> show errors
Errors for PACKAGE DBMS_STATS_INTERNAL:
LINE/COL ERROR
455/5 PL/SQL: SQL Statement ignored
466/40 PL/SQL: ORA-00942: table or view does not exist
1292/5 PL/SQL: SQL Statement ignored
1293/10 PL/SQL: ORA-00942: table or view does not exist
SQL>
Apparently some view or table doesn't exist. I re-ran catalog.sql (ran without errors)
and catproc.sql which only errored (with the same error above) when trying to recompile
DBMS_STATS.
Since the procedures are wrapped I can't view the source to see what table/view is causing
the problems. Any ideas would be much appreciated.

After digging a bit it looks like the correct script to build the WRI$ tables is doptim.bsq. I ran it and didn't look close at the output and since the missing table was now created I recompiled the DBMS_STATS package, but received another ORA-00942 error. Looking at the trace file I see that the missing table now is WRI$_OPTSTAT_AUX_HISTORY. I ran the script again and spooled the output (like I should have the first time) and found the following error:
SQL> Rem Aux_stats$ history
SQL> create table wri$_optstat_aux_history

3 savtime timestamp with time zone,
4 sname varchar2("M_IDEN"),
5 pname varchar2("M_IDEN"),
6 pval1 number,
7 pval2 varchar2(255),
8 spare1 number,
9 spare2 number,
10 spare3 number,
11 spare4 varchar2(1000),
12 spare5 varchar2(1000),
13 spare6 timestamp with time zone

16 enable row movement
17 /
sname varchar2("M_IDEN"),
ERROR at line 4:
ORA-00910: specified length too long for its datatype
I have to admit that the above has me stumped. I looked at another one of my databases and the column
sname is defined in the database as varchar2(30). What's with the size of "M_IDEN")?
