linker errors with stl in OSX 10.1.1

[Zesty]

Hey all-

Anyone doing STL work with c++ on MacOSX? I'm trying to compile a test program that uses ropes, but I get a linker error:

[toad_hall:~/projects/c++] zesty% c++ ropetest.cpp
/usr/bin/ld: Undefined symbols:
__t4rope2ZcZt9allocator1Zc._S_min_len

The code is:

#include <iostream>
#include <rope>

int main(void)
{
crope r(1000000, 'x');

crope r2 ;
r2 += r + "abc" + r;

crope r3 = r2.substr(1000000,3);
cout << r3 << endl;

cout << "this may take awhile...." << endl;
crope r4 = r2.substr(1000000,1000000);
reverse(r2.mutable_begin(), r2.mutable_end());
cout << "done." << endl;

return 0;
}

Anyone else had problems with the STL that comes with OSX? I was going to try setting up STLPort, but since both are based on the SGI version, I kinda figured it wasn't worth it.

Thanks for any info,

Zesty
