This is indeed a problem. EMBOSS will look in one directory for ACD files - 
normally the share/EMBOSS/acd directory under the install directory.

You can define another location using environment variables ... but that would 
be for *all* EMBOSS applications.

EMBASSY applications (mse, topo, phylip, end so on) are built under 
embassy/mse but installed in the same directories as EMBOSS.

embInitP will not modify the standard settings ... and I don't really like a 
fixed path in the code :-)

You can use (csh and tcsh):

setenv EMBOSS_ACDROOT /usr/share/myapp/acd/

... but that redefines the location for all ACD files.

That is the solution we would recommend.

We could find ways to code around it and offer an alternative directory to 
search ... but it would slow down all other applications, and you can expect 
problems with finding data files if too many directories have to be searched.
