tclcl compile failure w/ Solaris 7

[Rik Flor <rflor@anet.com>]

I am trying to build and install ns-allinone-2.1b5 on the following
Solaris system:

Solaris 7 Sparc
gcc 2.8.1
libstdc++-2.8.1.1

A side note: For those Sparc gcc users, you need to modify the "install"
script so that the tcl and tk "configure" lines include "--enable-gcc".
Otherwise, it will try to use the Solaris cc compiler.

Anyway, back to my problem.  The compile goes fine until it gets to tclcl.
It then fails with the following:

rm -f embedded-tcl.cc
./tcl2c++ et_tcl ../tclbox/lib/tcl8.0/init.tcl > embedded-tcl.cc
ld.so.1: ./tcl2c++: fatal: libstdc++.so.2.8.1.1: open failed: No such file
or directory
*** Error code 137
make: Fatal error: Command failed for target `embedded-tcl.cc'
tclcl-1.0b8 make failed! Exiting ...

Ideas as to what's going on here?  Hints and tips from existing Solaris 7
users would be very helpful <grin>

Thanks,
Rik
