ImageMagick --still some trouble

[andrea parmigiani]

Hi everybody.
    I'm new in the maling list.
I hope somebody can help me.

After having updated my OS from Tiger to Snow Leopard my macPort stoped 
working well. I'm experiencing some trouble trying to install 
ImageMagick. I have seen on the web that somebody else had the same 
trouble and I have already tried all what I could (clean all the ports, 
install the macPort version for SnowLeopard and many others )... but 
ImageMagick doesn't want to be installed. 

Here the error message that I get:

Error: Checksum (md5) mismatch for bigreqsproto-1.1.0.tar.bz2
Error: Checksum (sha1) mismatch for bigreqsproto-1.1.0.tar.bz2
Error: Checksum (rmd160) mismatch for bigreqsproto-1.1.0.tar.bz2
Error: Target org.macports.checksum returned: Unable to verify file 
checksums
Error: Status 1 encountered during processing.
Before reporting a bug, first run the command again with the -d flag to 
get complete output.


by any chance anybody has some advise?

thanks a lot

Andrea
