setting env variable from Guile

[Aurelien Chanudet]

Hi all,

I have a dynamic library located in a non standard
place I'd like to load within guile using
"dynamic-link". The dynamic link editor can be told
where to look for the library using an environment
variable. Is there a way to set up the environnement
variable directly _from_ Guile using for instance the
"system" primitive ?

Thanks,
Aurelien
