Here is the solution for amsn-svn work fine on gentoo 64 bits.
You must have:
Install openssl tcl and tk (with USE truetype ) with emerge.
emerge openssl tcl tk
After that you must compile tls by hand. And put this option:
./configure --with-tcl=/usr/lib64 --with-tclinclude=/usr/include --with-ssl=/usr/lib64 --enable-64bit
make && sudo make install
In the option of amsn > tab advance (the last ) > Section Others > put this line for TLS:
And it's ok, now amsn-svn work fine,no TLS wizard dialog box, connexion is Ok, can meet friends.
