During startup, im receiving this error:

----
Ive added the following lines hoping it would clear the error, but it doesn't appear to have any impact (I do have that file in that directory).
unmanagedClasspath in Compile <++= baseDirectory map { base =>
val lib = base / "native"
Seq(
lib / "libsigar-universal64-macosx.dylib"
)
}

Currently using jdk1.7.0_75

Any help would be great, thanks in advance

Turns out things were getting provisioned properly, just a noisy error.

Hi,

the sigar-loader library will try to load sigar first, and if it fails then it will provision and load the appropriate native library and then instantiate sigar again so, the first failure that always happens is causing the error you see, but then after that it is correcting the problem by provisioning and then loading, so that is something we should change though.. it looks like there is an error, but there actually isn't any

cheers,

Diego
