Fatal Format Error

[James Thompson]

Still attempting to share a texmf tree between fpTeX and teTeX (win,
linux, solaris installs). 

Currently the solaris and linux binaries are both happy with the .fmt
files in texmf/web2c/*.fmt which originally came from the teTeX distro.  
The fpTeX binaries however give

(Fatal format file error; I'm stymied)

If I build the format files via fpTeX's initex then fpTeX binaries work
but the solaris/linux binaries start giving the same error.

Can these files not be shared?  And if not then how can I get the distro's
to look at different copies of fmt files?

Sorry for all the questions lately.  I've been reading the docs, the FAQs,
etc. but I must not be looking right as I'm not finding answers.  I must
say that TeX and I just don't get along.  :(

Thanks,
James

PS If anyone is currently sharing a texmf tree between teTeX and fpTeX I'd
appreciate it if you could give me any pointers on how you did
it.  Thanks.
