[Bioc-devel] Bug in metaArray package

Hi,
I am the maintainer of oneChannleGUI. For data mining in my package I 
have an implementation of  IC coefficient derived from metaArray package.
To run intcor function I use an Object of class mergeExpressionSet 
created with two expression sets and the function mergeExprs:
 > metaData
ExpressionSet (storageMode: list)
assayData: 31 features, 200 samples
  element names: exprs
phenoData
  sampleNames: GSM282373, GSM282374, ..., GSM282572  (200 total)
  varLabels and varMetadata description:
    Name: Name
    FileName: FileName
    Target: Target
featureData
  featureNames: 200737_at, 200738_s_at, ..., AFFX-HUMGAPDH/M33197_M_at  
(31 total)
  fvarLabels and fvarMetadata description: none
experimentData: use 'experimentData(object)'
Annotation: hgu133a.db
ExpressionSet (storageMode: list)
assayData: 31 features, 204 samples
  element names: exprs
phenoData
  sampleNames: GSM308256, GSM308257, ..., GSM308460  (204 total)
  varLabels and varMetadata description:
    FileName: FileName
    Target: Target
featureData
  featureNames: 200737_at, 200738_s_at, ..., AFFX-HUMGAPDH/M33197_M_at  
(31 total)
  fvarLabels and fvarMetadata description: none
experimentData: use 'experimentData(object)'
Annotation: 

to run intcor I use the metaArray function intcor:
merged.cor <- intcor(metaData)
At this point I get the following error:
Error in .C("intcor", as.double(unlist(expr)), as.integer(unlist(cl)),  :
  C symbol name "intcor" not in DLL for package "metaArray"

If I run intCor from the MergeMaid package:
merged.cor <- intCor(metaData)
No errors are encountered.
It seems to me a problem in call of the C function.
Cheers
