Undefined symbol XpmReadFileToImage

[hce <webmail.hce@gmail.com>]

Hi,

I've installed libxpm-dev, but I've got an error of undefiend symbol
XpmReadFileToImage when I was running VLC plugin on Opera. After
searching, I find following packages, which one should I install to
fix the undefined symbol XpmReadFileToImage?

$ apt-cache search libxpm
jwm - Very small lightweight pure X11 window manager with tray and menus
libimlib2 - powerful image loading and rendering library
libimlib2-dev - Imlib2 development files
libxpm-dev - X11 pixmap library (development headers)
libxpm4 - X11 pixmap library
libxpm4-dbg - X11 pixmap library (debug package)

Thank you.
