yes.

no. but this may be a wording issue. if you compile libtachyon
with png and jpg support contains references to functions in libjpeg,
libpng (and libpng contains references to libz), so you have to
specify them, VMD requires them to link. the VMD build system
cannot detect this automatically and since john prefers to build
without those (for good reasons that he explained) the VMD config
does not contain any references to those.

hope that clears up matters,

VC> jpeg and png libs. Please correct me if I am wrong.
