[Mailman-Developers] error at make install

[Giorgos Sakalis]

I am trying to instal mailman 2.1 on an SGI O2.
When I execute make install i get this error

Creating language directory /usr/local/mailman/sv
mkdir /usr/local/mailman/sv
Cannot create directory "/usr/local/mailman/messages/de": File exists
Cannot create /usr/local/mailman/messages/de/#inst.170827# - Not a directory
*** Error code 2 (bu21)
*** Error code 1 (bu21)

Any ideas?
