Sorry,

For compiled in defaults there is some support for expansion, see 
Config::get_default() in common/config.cpp.  In particular the following 
should work: "<$HOME|.>/.guix-profile/lib/aspell. Due to the way the 
code is written an alternative must always be given, in particular 
"<$HOME>/.guix-profile/lib/aspell" is unlikely to work.  You could also 
use: "<home-dir>/.guix-profile/lib/aspell".  Note that the expansion is 
only for compiled in defaults, if the value is manually set, then there 
is no expansion.

When you do "aspell --config" it will print the defaults and then also 
what it expands to.
