[plt-scheme] Trouble compiling current PLT on Freebsd

I'm unable to get PLT Scheme svn revision 2146 to compile under freebsd. 

It the change that causes the problem seems to have been incorporated with version 2142 as 2141 compiles just fine.

I get a segment fault while it's running setup.

The last few lines of output are:

if [ -d ./../teachpack ] ; then  cp -r ./../teachpack /usr/local/plt/teachpack ; fi
cp -p ./../install /usr/local/plt/install
make lib-finish
echo /usr/local/plt/lib
/usr/local/plt/lib
make finish-stub
cd /usr/local/plt; ./install
Running setup...
Segmentation fault (core dumped)
*** Error code 139

Stop in /usr/extra/plt/src.
*** Error code 1

Please feel free to contact me directly if you need more information.
