[Rd] R_LIBS_USER bugs

[Jens Elkner]

Hi,


Having currently a big problem with R 2.10.1 vanilla (Solaris):

As soon as the R_LIBS_USER env var gets bigger than 1023 chars R
completely ignores it and uses the default:

> Sys.getenv('R_LIBS_USER');
                                          R_LIBS_USER 
"${R_LIBS_USER-~/R/i386-pc-solaris2.11-library/2.10}" 


The strange thing is, if I set another envar to the same value, there
seems to be no problem at all.  E.g.:

BLA=/develop/lnf/i386/R/LNFr-car/reloc/R-2.10/library:/develop/lnf/i386/R/LNFr-Formula/reloc/R-2.10/library:/develop/lnf/i386/R/LNFr-lmtest/reloc/R-2.10/library:/develop/lnf/i386/R/LNFr-sandwich/reloc/R-2.10/library:/develop/lnf/i386/R/LNFr-strucchange/reloc/R-2.10/library:/develop/lnf/i386/R/LNFr-zoo/reloc/R-2.10/library:/develop/lnf/i386/R/LNFr-dynlm/reloc/R-2.10/library:/develop/lnf/i386/R/LNFr-ineq/reloc/R-2.10/library:/develop/lnf/i386/R/LNFr-KernSmooth/reloc/R-2.10/library:/develop/lnf/i386/R/LNFr-np/reloc/R-2.10/library:/develop/lnf/i386/R/LNFr-plm/reloc/R-2.10/library:/develop/lnf/i386/R/LNFr-pscl/reloc/R-2.10/library:/develop/lnf/i386/R/LNFr-ROCR/reloc/R-2.10/library:/develop/lnf/i386/R/LNFr-sampleSelection/reloc/R-2.10/library:/develop/lnf/i386/R/LNFr-systemfit/reloc/R-2.10/library:/develop/lnf/i386/R/LNFr-tseries/reloc/R-2.10/library:/develop/lnf/i386/R/LNFr-urca/reloc/R-2.10/library:/develop/lnf/i386/R/LNFr-quantreg/reloc/R-2.10/library:/develop/lnf/i386/R/LNFr-mvtnorm/reloc/R-2.10/library:/develop/lnf/i386/R/LNFr-leaps/reloc/R-2.10/library

Any hints, what magic is going on here?
