That's odd... the shmat messages have to do with shared memory (which
GTK tries to use for faster display; your X server might not support
it).
If the red squiggles are showing up, it means the fonts are found and
the metrics are good (since the squiggles are drawn to the length of
a misspelled word). I'm not intimately familiar with the Sun X servers,
but they do include some PostScript extensions.
You might try looking at /usr/local/AbiSuite/fonts (or wherever the
fonts got installed) and manually running "makepsres" to re-generate
the font metric info for X.
If this fixes the problem, I might have to modify the Solaris package
setup to make sure this happens on each install.
