Error opening Terminal: vt100

[Christoph]

Hi,

I have sucessfully compiled mutt 1.2.5i on MacOSX 10.0.
But when I try to start mutt I get this error message:
Error opening Terminal: vt100. I tried setting $TERM to
vt220 etc. but no success either. I can remember having
a similar error message, when I installed lynx but this 
is months ago and I forgot how I fixed it. Can somebody
help me?

TIA
Christoph
