List,

As a courtesy to others with similar problems, here's a problem summary and 
solution.  (Thanks to Steve Woodbridge for the ongoing support!)

Problem summary:
     System: FreeBSD
     Access: No root access, but local builds okay
     Mapserver version: 3.6.1
     Goal:  Build mapserver with true type support.
     Issue:  Machine has an existing version of Freetype 2.x at the system 
level. The ./configure routine recognizes the Freetype 2.x rather than the 
(required) Freetype 1.x even when statically pointed to the Freetype 1.x 
libraries.

Problem solution:
     All of the following steps were required to successfully build mapserver 
in the above environment...
     1) Compile GD 1.8.4 and Freetype 1.3.1 to local directories.

     2) In the .login, add:
     # Added for mapserver purposes:
     setenv LD_LIBRARY_PATH /path/to/libttf.so.4.0
     # End of mapserver additions.

     3) Configure mapserver with the following parameters (plus any others you 
want):
     ./configure --prefix=/path/to/libraries 
                 --with-gd=static,/path/to/libraries 
                 --with-freetype=/path/to/freetype 
                 --enable-force-freetype1 
                 --enable-runpath 
                 --with-proj 
                 --with-tiff

     4) Edit the resulting mapserver Makefile as follows:

     # These originally pointed to root-only system directories.
     # Change them to your local installation directories.
     LIB_INSTALL=/usr/home/gisweb/local/lib/
     HEADER_INSTALL=/usr/home/gisweb/local/include/mapserver-3.5/

     # Proj.4 distribution (cartographic projection routines).
     #PROJ_INC  <-- originally blank.  Needed the reference as shown on line 
below.
     PROJ_INC=-I/usr/local/include 
     PROJ_LIB= -lproj
     PROJ=     -DUSE_PROJ -DUSE_PROJ_API_H

     # GD distribution (graphics library GIF and/or PNG support). (REQUIRED)
     #
     GDFONT_OBJ=gd-1.2/gdfontt.o gd-1.2/gdfonts.o gd-1.2/gdfontmb.o gd-
1.2/gdfontl.o gd-1.2/gdfontg.o
     GD_INC=  -I/usr/home/gisweb/local/lib
     #GD_LIB=   -ljpeg -lfreetype -lpng -lz  <-- originally refers to -
lfreetype.
     GD_LIB= -lm -lgd -lpng -lz -ljpeg -lttf 
     GD=       -DUSE_GD_PNG -DUSE_GD_JPEG -DUSE_GD_WBMP -DUSE_GD_TTF
     GD_STATIC = /usr/home/gisweb/local/lib/libgd.a

     # TIFF distribution (raster support for TIFF and GEOTIFF imagery). 
(RECOMMENDED)
     TIFF_INC= 
     #TIFF_LIB= -ltiff -ljpeg -lpng -lz -lfreetype  <-- originally has -
lfreetype
     TIFF_LIB= -ltiff -ljpeg -lpng -lz -lttf
     TIFF=     -DUSE_TIFF

     5) From the mapserver-3.6.1 directory containing the modified Makefile, 
type:
     make install
     make

     6) Typing "./mapserv -v" should return the following (Note "SUPPORTS=TTF"):
     MapServer version 3.6.1 OUTPUT=PNG OUTPUT=JPEG OUTPUT=WBMP SUPPORTS=PROJ 
SUPPORTS=TTF SUPPORTS=WMS_SERVER INPUT=TIFF INPUT=EPPL7 INPUT=JPEG 
INPUT=SHAPEFILE

     These steps eliminated the problem of the incorrect True Type angles when 
using the ANGLE AUTO parameter in a LABEL object.

     Hope this helps others with similar problems.

     Thanks again to all who offered support.
