# <nacl source>/build/<hostname>/lib/<arch>/libnacl.a

|
# <nacl source>/build/<hostname>/include/<arch>/crypto_box.h

|
||
|
|
# compiled on.
|
||
|
|

||
|
|

|
||
|

# handle it. Here we only install one copy, based on if you're a
|
||
|
|
# 64bit system or not. A --universal could come later though I guess.
