davfs2 and libgssapi.so.2

[cref]

I'm trying to mount a webdav folder. After I install the davfs2, I use mount.davfs. And the error message says "mount.davfs: error while loading shared libraries: libgssapi.so.2: cannot open shared object file: No such file or directory". It seems that the problem is from two conflict package krb5 and heimdal, and most of my current packages (samba,openssh) rely on krb5, so I cannot replace it with heimdal( At least it seems so). So I tried to make a symbol link from libgssapi_krb5.so.2 to libgssapi.so.2 , but the program still ask libheimntlm.so.0. I've also tried to install libgssglue and it's not work too. Anyone can help me out?
