I have now a Fink package for asymptote 1.92 that builds both on 10.5 
and 10.6.

On 10.5, it did not build, because asymptote-1.92, contrary to 1.91, 
includes <tr1/unordered_map>. The version of this that comes from 
c++-4.0.1 is apparently either incompatible with gc or just broken. It 
spits out long and incomprehensible error messages of the type

and so on.

So for 10.5, I had to patch memory.h so that it does not include 
<tr1/unordered_map>. On 10.6, this is not necessary.

I also patched pipestream.h so that it uses SIGINT instead of SIGQUIT 
and the latex crash dumps go away.

If I have more time, I will take this to the asymptote authors.
