DSP Link

Using the latest software acts strangely.  When building DSPLink (http://tiexpressdsp.com/index.php/Building_The_OMAP-L137_SDK)  I get an odd message when I do the platform configuration step with the perl script. 
This is part of the reason why I'd like to revert back to the beta version of the software. 

step 2 Configure what platform you are building DSPLink for: 
host $ cd $DSPLINK    
host $ perl config/bin/dsplinkcfg.pl --platform=OMAPL138 --nodsp=1 --dspcfg_0=OMAPL138GEMSHMEM --dspos_0=DSPBIOS5XX --gppos=ARM --comps=ponslrmc --DspTskMode=1

  !!DSPLINK will be configured for Build OS: LINUX!!

  DSPLINK variable is not set!!
  Please set it:
        On Windows:
                set DSPLINK=<path to DSPLINK base directory>
        On Linux:
                export DSPLINK=<path to DSPLINK base directory>

I managed to get the latest version of the Software to partially build (GPP side build fine).  Still having trouble with getting the DSP side to build.

Step 5: Building the DSP-side DSPLink modules and example applications:

Go to the source directories for the dsp and build the DSPLink modules

host $ cd /home/<useracct>/OMAPL13#_arm_1_##_##_##/dsplink-1_6#_##-prebuilt/packages/dsplink/dsp/src
host $ /home/<useracct>/OMAPL13#_arm_1_##_##_##/xdctools_3_1#_##_##/gmake

Compiling failure.c...
"failure.c", line 45: fatal error #5: could not open source file "std.h"
  #include <std.h>
                  ^

1 fatal error detected in the compilation of "failure.c".
Compilation terminated.

The TI guide (http://tiexpressdsp.com/index.php/Troubleshooting_DSPLink_build_issues#Problem:_DSP-side_build_error_in_std.h) talks about this error.  Can someone explain what is meant by "Ensure that the correct DSP/BIOS path has been given in the distribution makefile".  Do I have to specify a path to a certain variable?  Please advice.
