First, I assume your emboss.default file has:

SET emboss_tempdata /local/share/EMBOSS/test

Next, you can try:

seqret -debug

This will write a file seqret.dbg  where I would expect lines like this:

directory '/local/share/EMBOSS/test/embl' entry 'hs*' acc 'hs*'
ajFileNewIn '/local/share/EMBOSS/test/embl/division.lkp'
ajNamResolve of '/local/share/EMBOSStest/embl/division.lkp'

This is the division file which it says cannot be opened.

If you see what appears to be the right filename, check file (and
directory) protection.

If you see something else, it may give a clue to where the setup is wrong,
or you can get help from emboss-bug at embnet.org
